Facebook Rules

Built my facebook fanpage, am i allowed to put images up which arent mine?
The page is about cars so its difficult to even buy photos which dont have some sort of car logo on, what do i do!?

In the About section of your page put something like:" Pictures that we post on our page are not our property and the belong to their owners. This is a fan page and we don't bla bla bla....If you feel like we violated your ownership please let us know and we will delet the image from our page" and you will be ok

Thanks, i will do that now!
