Snap rejects creative dominated by text overlays, low-resolution graphics, or flashing imagery. Catalog item images that double as ad creative must hold to the same editorial bar as Snap Ads.
Snap Catalog Manager requires product images that are publicly reachable, sized within the platform's bounds, in supported formats (JPEG/PNG typically), and free of overlays, watermarks, retailer logos, or text callouts. This issue trips when one of those constraints is broken.
