# Check your photo against Galaxus's rules.

Galaxus sets rules for the main image that can be measured from the photo: background colour. Drop a photo to see which ones it meets. It runs in your browser; nothing is uploaded.

## Choose a marketplace and a photo.

Rules come from each marketplace's own help pages, summarised in the [guides](https://herofab.app/guides/) (checked 24 September 2026). Size, file size and format are checked as well.

## What Galaxus asks for.

- **Main image:** The product cut out, on a plain background
- **First image:** Good resolution, the product cut out (freigestellt), seen from the front
- **Why cut out:** Galaxus gives every cut-out image the same background colour so it blends into the shop page
- **Selection:** Galaxus has used AI to select and process images since early 2023

## How each rule is measured.

- **Background colour:** The background colour is the median of a thin band along all four edges. A pure-white rule passes only when that band is RGB 255, 255, 255; near-white values such as 253 are reported with their exact colour.
- **Scene photos:** Room and lifestyle photos have no plain background to measure against, so fill, edges and shadow are marked as not measured rather than guessed.
