“熟” means “ripe, cooked or done” and “图” means “pictures.” “熟图” means “edited or retouched pictures,” and the opposite is “生图” which means “raw, original pictures.”
Like steak, pictures can range from “rare” to “well done.” The former means that though a picture is slightly retouched, people cannot tell the difference between it and the original, whereas the latter refers to a picture that is unrecognizable from the original after a complete retouching.
