Feature Callout Photos: Empty Spec Bands, Same SKU, Off MAIN

A feature-callout still is a secondary listing photo that answers “what is this part?” with the same SKU you sell and two to four empty bands an editor will fill from the spec sheet. It is not MAIN, not a scale still, not a packing list, and not a poster of invented watts, IP ratings, or “#1 2026.” Lock the true features from the carton first. Leave the words out of the pixels. Amazon’s product image help (as of 2026) still wants MAIN to be a realistic image of the actual product on a white field (RGB 255, 255, 255), the item filling most of the frame, JPEG/PNG/TIFF, and enough pixels for zoom (plan 1,000 px or more on the long edge). Additional images can show the product in context and infographic layouts. OpenAI launched ChatGPT Images 2.5 on September 8, 2026, and said it keeps a subject more stably while you change one element—use that to add empty callout bands, not a second gadget. Amazon set Prime Big Deal Days for October 6–7, 2026; callout stills need to match the unit that ships, not wear fake “50% off” or “Lightning Deal” bursts. FreeGPTImg is a GPT Image 2 workspace: 20 daily free credits, no credit card required. Overlay real specs last.

Draft the still in FreeGPTImg. Keep materials honest in AI product photography, cut a listing crop in the Amazon product photo generator, lock a clean field in the white-background product photo tool, upload a locked hero into image to image when you only add bands, leave claim boxes empty in the AI infographic maker, stay on GPT Image 2 for the loop in front of you, invent the first layout in AI text-to-image, and recrop a social cut only after the catalog still is honest. Do not put callouts on MAIN.

What a feature-callout still actually does

Shoppers opening a Bluetooth speaker, a 500 ml bottle, or a silicone stand are answering “where is the port, the gasket, the carry loop—and is that even on this unit?” The still answers with the same product and empty leaders pointing at parts that exist. MAIN answers with the product as sold—usually assembled, on white, filling the frame. A scale still answers size with one honest reference. A what's-in-the-box still counts parts that ship. A how-to still is one real action. A callout still is parts and empty spec bands, not a sale poster.

The bands are a layout, not a claim. If the speaker has one USB-C port on the back, do not generate a second port “for balance.” If the bottle lid is a screw cap, do not invent a sport nozzle. If the stand does not include a phone, do not park a flagship with a readable logo in the frame. A comparison board of two SKUs is a different job. A full A+ module with lifestyle scenes is a different job. This still is one offer, two to four empty rectangles, thin leaders, and the true silhouette.

ChatGPT Images 2.5 can keep a subject while you change one layout. That is the callout job: keep the speaker, add empty bands. It is not permission to add a Prime smile, a five-star strip, or a competitor’s badge. FreeGPTImg runs GPT Image 2. Write the model you used into the file name.

Do not prompt studio wordmarks, “best of 2026” bursts, medical seals, or prices. Photorealistic AI people are a separate policy: if a marketplace requires a contains-synthetic-performer tag in IPTC/XMP, apply it in an editor. Prefer a quiet tabletop and the product itself. Never generate a child holding a callout board.

Pick one slot before you generate

Weak callout sets fail because they ask for a white MAIN, four numbered specs, a lifestyle room, a sale burst, and a second SKU in one pass. Name the slot first.

Slot job	Working crop	Start from	Change one thing	Keep	Wrong move
Two-band callout	Square or 4:5	Locked hero of the same SKU	Two empty bands + thin leaders	True silhouette, empty labels	Watts, IPX, “fast charge” in pixels
Four-band spec board	4:5, empty rectangles	Same SKU, same lighting	Layout into four empty boxes	Empty numerals, empty units	Model-written “20W,” “48h,” “IPX7”
Part close-up + one band	Square	Same SKU	One empty band on one true part	True port, gasket, or grille	Extra ports, fake LEDs, extra buttons
MAIN (not callout)	Square, white field	Product as sold	Crop only	Pure white, no arrows	Putting leaders or boxes on MAIN
Social recrop	1:1 or 4:5 or 9:16	One callout still	Crop only	Empty headline	Baking “50% off” into pixels
Comparison (different job)	Leave it	Two SKUs is not this still	—	—	“vs,” five stars, “better than”

MAIN is not a spec poster. A four-band board is not MAIN. A lifestyle room is not a callout. Generate large, then recrop in an editor to the box the channel shows. Overlay real words later. Watts, milliliters, IP ratings, hours, URLs, prices, “limited-time,” “Lightning Deal,” and “bonus” never belong in the generator if they must be exact.

Amazon’s help still treats MAIN as the product as sold, without text, logos, borders, or watermarks covering the item. Additional images have more room for infographic layouts, but they still should not carry review stars, free-shipping claims, seller-specific badges, or prices. Recheck the live help article before you upload. Empty bands are the cheap way to stay inside that line while you wait for a manager to sign the overlay.

Feature-callout workflow

Use the same sequence in product-photo tools, an image-to-image pass, a GPT Image 2 tab, or ChatGPT Images 2.5.

1. Write the offer in five lines. SKU truth (one offer, true materials, true pack count), the real parts you will point at, slot name, crop, empty type zones. If a feature is not on the carton or the measured sample, it is not in the overlay later either.
2. Lock one as-sold hero. White field, even light, product filling most of the frame. This still is MAIN. Do not put arrows, boxes, or sale bursts here.
3. Write keep / change / do-not. Keep silhouette, materials, finish, port count, and the exact SKU. Change only the empty-band layout. Do not add logos, seals, QR codes, Prime marks, ranking bursts, extra products, or extra accessories.
4. Generate one two-band callout from the locked hero. One pass, two empty rectangles, thin leaders to real parts. File names like speaker-callout-two-band.jpg. If turn two invents a third port, revert to the locked hero and try again.
5. Optional four-band spec board. Same lighting, same SKU, large empty rectangles. Do not let the model write “20W,” “IPX7,” “48-hour battery,” or “BPA-free.” Overlay those in an editor after someone reads the spec sheet.
6. Match the crop. Square for many gallery files. 4:5 for a tall board. 16:9 only if that is the module you actually upload. 1:1 or 9:16 for a social recrop. Do not stretch a white MAIN into a Story and call it a callout.
7. Inspect the parts before mood. A USB-C that became Lightning, a gasket that vanished, a sixth finger on a hand, or a band reading “20.00W” are stop conditions. Hold the still next to the real product. If a stranger would think this unit has a feature it does not, discard it.
8. Overlay copy last. In an editor, set the real feature names and only the claims a manager signed. Keep marketplace files in the format that channel lists (often JPEG or PNG, RGB, enough pixels for zoom).

OpenAI’s Images 2.5 notes still help if you never open ChatGPT: keep the subject, edit one element, expect earlier choices to survive later turns. That is a callout rule. Add the empty bands. Do not invent a second speaker.

Amazon’s October 6–7, 2026 Prime Big Deal Days window is a deadline for honest feature stills, not a brief to stamp “Deal” or “50% off” on the pixels. Deal copy lives in Seller Central. The photo still has to look like the product that ships. A fake IP rating is a return and a policy risk, not a conversion trick.

Prompt formula

Catalog feature-callout still, not a MAIN hero and not a “20W / IPX7!” poster.
Product: one [SKU], accurate silhouette, materials, port count, and pack count.
Callouts: [two empty bands / four empty rectangles / one empty band on one true part].
Slot: [two-band callout / four-band spec board / part close-up / MAIN as-sold / social recrop].
Light: even catalog light for boards; one honest indoor lamp only if the slot is a single in-use crop.
Keep: empty numerals, empty unit bands, empty “hours / watts / IP” lines.
Change only: [the empty-band layout / the one close-up crop].
Text in image: none. No watts, IP ratings, prices, QR codes, watermarks, or marketplace badges.
Do not add: extra SKUs, extra ports, five stars, Prime logos, sale bursts, celebrity hands.

Prompt examples

Two-band speaker. “Square catalog still of one charcoal fabric Bluetooth speaker, even studio light, quiet white field. Two large empty rectangular callout bands with thin leaders to the fabric grille and the rear USB-C port. No extra ports, no phone, no Prime badge, no ‘20W’ type.”

Four-band bottle board. “4:5 catalog board of one 500 ml matte bottle, identical lighting, quiet white field. Four large empty rectangles along the right edge. No printed ‘BPA-free,’ no ‘24h cold,’ no prices, no ‘new’ bursts.”

Part close-up, one band. “Square catalog close-up of the same silicone stand’s cable notch, true size, even studio light, quiet light-gray field. One empty callout band. No branded phone, no extra notches, no ‘fits all phones’ type.”

Image-to-image, bands only. “Image-to-image: keep this exact speaker silhouette, fabric, and studio lighting. Add only two empty rectangular callout bands with thin leaders to the grille and the USB-C port. Quiet white field. No extra objects, no text, no second speaker.”

MAIN, as sold. “Square catalog still of the same speaker standing assembled, true charcoal fabric, even studio light, pure white background RGB 255 255 255. Product fills most of the frame. No arrows, no boxes, no readable slogans.”

Social recrop. “9:16 recrop of the two-band still, speaker in the middle third, empty lower band for later overlay. No ‘50% off’ type, no percentages, no platform UI chrome.”

Review the pixels before you upload

Zoom to 100%. A phone grid hides a fake port.

• Subject honesty. Same silhouette, fabric, finish, port count, and SKU. Only the parts you named. If a stranger would think this unit has a feature it does not ship, discard the still.
• Slot honesty. White MAIN stays as-sold and unpropped. Callouts stay off MAIN. Lifestyle shows one hero item unless the SKU is a set you actually pack.
• Empty type. Watts, IP ratings, hours, milliliters, prices, and marketplace badges stay empty of anything you need people to read.
• People and file. No recognizable generated faces you cannot clear. No children. JPG or PNG, RGB, enough pixels for zoom, no watermark, no QR. Preview on a phone and as a square.
• Provenance. OpenAI still uses C2PA metadata and an invisible watermark on GPT Image outputs. Downstream apps may keep, strip, or flag that data. A prettier callout is not a license.

Limitations you should not skip

A generated still is not marketplace approval, not a spec-sheet substitute, and not a commercial-rights grant. FreeGPTImg does not upload into Amazon, Shopify, or a retailer CMS. Do not upload someone else’s callout photo “to see the style,” and do not imitate a competitor’s badge set. If a platform requires AI disclosure, follow that policy. ChatGPT Images 2.5 is not GPT Image 2; on FreeGPTImg you are in a GPT Image 2 loop. If turn three adds a third port, revert. Do not generate medical, “#1 2026,” or “Lightning Deal” badges unless those claims are already on the real label and a manager signed them. Recheck live marketplace help for MAIN background, file type, additional-image rules, and pixel floors before you publish.

FAQ

What is a product feature-callout still?

It is a secondary catalog still that points at real parts of one SKU: a two-band crop, an optional four-band spec board, a part close-up, and a recrop if you need social. It is not MAIN. MAIN is the product as sold. FreeGPTImg runs this on GPT Image 2, with 20 daily free credits and no credit card required.

What size should I generate?

Do not treat a social crop as your only canvas. Plan 1,000 px or more on the long edge for marketplace files, square for many gallery stills, 4:5 for tall boards, and 1:1 or 9:16 only as recrops. Confirm the live help article for the channel you publish to. Stretching a white MAIN into a Story is how the leaders fall out of the frame.

Should I put “20W / IPX7” in the image?

No. Exact specs belong on the spec sheet or overlay after someone reads the carton. Leave those rectangles empty. Invented watts and IP ratings are a review risk and a returns problem.

Can the callout board be MAIN?

Usually no. MAIN is the product as sold on a white field, without extra arrows or spec boxes. Put the callouts in an additional-image slot. If the offer is a set, MAIN can show the set as sold—not a comic of four badges plus a sale burst.

Can I add “Lightning Deal” for the October sale?

No. Prime Big Deal Days on October 6–7, 2026 is not a reason to generate a deal badge, five stars, or a price. Generate only the product and empty bands. Deal copy stays out of the pixels.

Why did the model invent a second USB port?

The prompt asked for “feature-rich,” “pro spec,” or “callouts on every side” without locking the true port count. Shorten it. One offer. Two bands. Empty type. Generate again. If the ports still drift, lock a white-background hero of the real product first, then run image-to-image with “add two empty bands only, change nothing else.”
