Aren't you going to expand the information as well? This is a Wiki not a gallery site. Our top priority is information. Also when you upload new images you categorise them. For your recent uploads you want to insert categories "Tangled images" and Images from movies".
Images won't encourage people to put down information, just the opposite. Don't always expect others to do the writing for you. Sometimes you have do it yourself, and in opinion that's what you should be doing mostly. Pictures are not as important than the information.
