I've noticed that some teams put some photographic pictures (of female models for example) into their maps.

My question is, is it legal to do something like that? Grabbing elements from the internet and use it as a texture or part of a texture in maps/mods?
I for example plan to create an advertisement poster for a HL2 map and I would like to put a female model into it.
But I want to avoid any legal problems.
