Use an image you created, licensed, purchased with suitable rights, or received permission to use. A public image appearing in search results is not automatically licensed for reuse. The service cannot create rights for a copyrighted character, photograph, logo, or artwork supplied without permission.
Wide images usually fit a desktop theme better than tall phone wallpapers. Leave a calm area behind the main title and project list, keep the subject away from the composer, and avoid very small text inside the image. PNG, JPEG, WebP, HEIC, and HEIF are accepted up to 15 MB through private storage.
A Custom Skin order uses one submitted image and has no revision. If the image is unusable—for example, corrupt, too small, or clearly missing necessary rights—the delivery window begins after a suitable replacement is received.
