Background samples
Browse public Cube-16 background samples, filter them by category, read bilingual descriptions and download the JPG files.
Use a portrait JPG for the best background fit in Cube-16. A tall image, ideally 1080 x 1920 or larger, will display more cleanly, and the file must stay under 1 MB.

Client-side checks reduce accidental uploads: JPG signature, extension and file size are checked before a share or email draft is opened. Real malware scanning must still happen server-side if a backend upload is ever added.
