The rules
A photo that breaks a rule marked rejected is refused or suppressed; a recommended one is advice. The photo check measures each of them on your photo.
- Rejected At least 500 px on the longest side
- Rejected At most 26 megapixels
- Rejected In JPEG, PNG or WebP
- Rejected On a pure white background (RGB 255, 255, 255)
- Rejected No added text, logos, watermarks or borders — No logos, text, icons, watermarks or frames on the thumbnail.
More on Allegro
- Check by eye
- Some categories allow a uniform light grey thumbnail background; used or damaged items, auctions and digital products are exempt.
- A set must show every item in it and nothing extra.
- Use sRGB colour.
- The fix makes
- 2,000 × 2,000 px, JPEG, the product cut out onto white, filling 90% of the frame. Added text is painted out where the marketplace forbids it, and a photo under its minimum size is upscaled.
