Morphology

photobomb = bomb (semi-transparent) = photo + bomb

The noun is formed from the same playful photo + bomb structure, but its specific 'intrusive photograph' meaning is conventional rather than fully literal.

Etymology

Photobomb mixes photo (used in 'photograph' and related to 'light') and bomb ('explosion' or sudden surprise). A photobomb is the sudden person or thing that jumps into a picture, often as a joke that spoils or makes the photo funny.
