What Galaxus asks for.
Source: Galaxus — Wer bestimmt eigentlich die Bilder bei einem Produkt? (14 November 2024) · checked 24 September 2026
- 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.
