Why this matters
- The app rejects photos that are too small, then compresses accepted picks to WebP ≤ ~2 MiB.
- Prep images before upload (or ask an AI) — you'll avoid reject / warning dialogs.
- Attach your photo and paste the matching prompt below into any image-capable AI.

Quick heads up
Short edge = the smaller of width and height. Cover must stay wide (~2:1), not square.
AI prompt — dish / variant photo
Copy everything in the box. Attach your photo to the AI chat first.
Resize and crop this food photo for the Koolodoor partner app (dish / variant image).
Requirements:
- Output one image, JPEG or PNG.
- Short edge (min of width/height) must be at least 900 pixels (hard minimum 800).
- Prefer a square or near-square crop centered on the dish.
- Keep the food sharp and appetizing; do not add text, watermarks, or logos.
- Do not upscale a tiny blurry photo beyond recognition — if the source is far below 800px on the short edge, say so and ask for a higher-res original.
- Aim for a clean file under ~2 MB if possible.

In-app tips
- After Create Variant, add the dish photo before sync.
- Store cover & logo: Manage Store profile / branding fields.
- If the app warns (800–899 px short edge on a dish), re-export at ≥900 or use the dish prompt above.
