Keep the wonky rim: AI product photos for small webshops

The cup used here has a matte chalk-white finish above a bare unglazed foot ring. Its thin handle sits on the right. The rim dips slightly at the front left.

That small departure from the clean shape is exactly what a modern maker's customer is paying for. If a generated version straightens it, reject the picture even when the lighting suits your page.

Start with the cup you will actually send

For your own shop, start with your own photograph of the actual item for sale. We want enough space around the cup to read its outline. That includes the gap inside the handle and the point where the base meets the surface. Keep an untouched copy of that file beside your working images.

The flat lay needs a photograph taken directly overhead of the same cup. If you want to show the interior glaze, photograph it empty so liquid does not hide the inner wall. A separate close-up is worth taking when the rim is too small to inspect in the wider shot.

Before writing a prompt, note the features that identify this particular cup. The dip in the lip and the boundary above the bare foot ring give you precise places to compare later. The handle needs its own check. Describe only irregularities you can see; adding handmade character to a smooth cup would change the product.

The front and overhead “originals” below are AI-generated stand-ins made with Google Nano Banana 2.1 to demonstrate the method. For a listing, use your own photographs of the actual item for sale.

Choose the image's job before its background

We would give the clear product view the first gallery slot and let the kitchen scene follow it. That leaves room for atmosphere once the buyer has seen the whole cup. Check your destination's rules before choosing the background; a white backdrop alone does not settle whether an image belongs in a listing.

• Etsy: for most items, you need at least one unedited photograph of the actual item against a real background. AI-assisted edits are allowed for other images when they accurately represent what buyers receive. Keep your untouched photograph in the set. See Etsy's listing-image guidance.
• Shopify: product images can be up to 5000 × 5000 pixels or 25 megapixels, with a file size below 20 MB. Shopify recommends 2048 × 2048 pixels for square product images and consistent aspect ratios for featured images displayed together. Plan your crop using its product-media specifications.
• Amazon: its public photography guide advises a pure-white background in most cases and product coverage of at least 85%. Check your category's requirements before using an edited photograph as the main listing image.
• Google Merchant Center: its image specification requires AI-source metadata for generative imagery and says to retain relevant IPTC DigitalSourceType tags. Inspect the exported file before submitting it to a feed.

If you are still choosing the kitchen, sketch the setting with FLUX.2 Klein 4B at 2 credits per run. Leave the product out of this exercise so you can judge the counter space and direction of light without also checking the cup.

The empty counter sketch settles the setting for the coffee pour in #4. Pale oak sits against cobalt-blue cabinets, with a dusk window and under-cabinet light.

Attach your reference separately before running a cup prompt. Let that photograph govern the object if any detail in the wording differs from yours. If your setting idea is still a few rough notes, Prompt Crafter can help turn them into a prompt. Remove any product detail the draft adds beyond your photograph. For help with the wording, see the prompt-writing guide.

Give the white-background photo an honest edge

The cup edits (#2–#6) were made in the AI Studio on 10 November 2026 using the stand-in sources as references. Each had one run with its named model and the exact prompt shown; prompt rewriting was off.

Use the identical front photograph for both versions below and set each output to 1:1. Try the first with Google Nano Banana 2.1 and the second with OpenAI GPT-Image 2.6 Sunburst, each at 10 credits per run. Keeping the source and wording the same gives you a direct comparison of how each version handles the cup.

We would reject a tidier silhouette if it straightens the real rim. Follow the mouth from side to side before judging the lighting, then inspect the opening inside the handle. Its shape matters even when the outer colour looks familiar.

Enlarge the source and candidate until the rim appears the same width on screen. A shifted foot-ring boundary or invented speckles are reasons to reject the edit. A pale fringe around the outline needs attention too. If both versions change the cup, use the original front photograph in that gallery slot.

The Nano Banana version (#2) keeps the rim dip at the front left and the bare foot ring. Its thin handle retains the same open shape. Accept the silhouette after cropping off the stray grey curve running down the right edge.

The Sunburst version (#3) also keeps the rim dip and foot ring. The handle opening remains, and the cup sits larger in the frame. Accept this version for the white-background slot.

Let the lifestyle photo live on an ordinary counter

A clean pale oak counter gives this cup enough room. We would show someone pouring coffee at dusk, with a coral shirt against cobalt-blue cabinets. Keep the hand and carafe clear of the cup so its outline and handle remain visible.

The prompt uses your original front photograph again and allows the coffee to change its contents. In the listing caption, state that only the cup is included.

Keeping the photographed viewpoint gives you a visible surface to compare with the source. A new angle asks for parts of the cup that this photograph cannot show. If the other side belongs in your gallery, photograph it first.

The contact shadow should anchor the base to the oak. Compare the matte chalk-white finish with the source on the same screen. Warm kitchen light can affect its appearance, but a glossy surface would change the product. The photorealistic prompt examples offer other ways to describe light when you want to adjust the setting.

The coffee pour in #4 leaves the cup readable. Its outline and handle match the source. The bare foot ring also matches, and the matte finish reads.

Accept it as a lifestyle image. The rim dip is too small to confirm at this distance, so use another view to show that feature.

Use a real overhead view for the flat lay

We like an overhead view that leaves the mouth easy to inspect. Upload your overhead photograph of the same cup and keep the handle in its photographed position. If you only have a front view, take the overhead photograph before using this prompt; you need a source for the visible interior.

The hard morning sun should give the terrazzo a crisp shadow without losing the chalk-white rim in a bright patch. Compare the mouth's width with the body and follow the inside edge for a changed contour. Keep the blue stool at the edge of the frame so it cannot overlap the cup. The overhead prompt asks for the contents to stay unchanged. An empty cup should stay empty.

Run #5 places the cup on pale terrazzo in hard sun, with a cobalt-blue stool at the edge. It keeps the throwing spiral inside and the handle to the right. The mouth is rounder and more regular than in the overhead source. Reject this edit for a listing that sells the uneven rim; use the overhead source instead.

Put the rim back beside the reference

For the detail slot, we prefer a plain, sharp source crop to a polished image that changes the surface. Start with a close view of the real rim; if the texture is unclear, take a closer photograph before asking for an edited version. The close-up needs to show what your wider gallery view cannot.

The source rim crop here was cut straight from the generated front view, with no AI retouching or enlargement.

Place the untouched crop beside the generated detail at the same displayed rim width. Use the rim's slight dip as a fixed point while you compare its thickness and the matte texture below it. The pale oak shelf can soften into the background; the photographed edge needs to stay sharp. The Promptography article offers more context for using photographic language in your prompts.

Accept the picture only when the visible product features you checked agree with the source. If a feature has changed, mark that area in your working comparison so you can recognise the problem in another version. Keep that image out of the shop gallery.

In #6, the dip remains but is broader and smoother. The surface has fewer dark speckles and a smoother texture than the source crop. Reject the edit and keep the source crop for the detail slot.

Keep the photo that tells the truth

We judge the final selection in the shop's actual gallery layout. A close-up and a full view have different jobs, and each needs enough room to do its own. Check the phone crop for a clipped handle, then compare each exported file's dimensions and size with your destination's limits above. Save the prompt and model name alongside its reference filename so you can trace an edit later.

For this demonstration, choose #3 for the white-background slot, or #2 after cropping the right edge. Keep #4 for the lifestyle slot. Use the overhead source in place of #5 and the source rim crop in place of #6; both edits are rejected.

The article copies are 1024 px wide JPEGs: #2 and #3 are 1024 × 1024, while #4 is 1024 × 764. The Studio returned the white-background pair at 1024 × 1024 and #4 at 1200 × 896.
