Peanuts fansite

I am thinking about making a fansite for the populair comic strip Peanuts. The site would consist of collecting virtual peantus clip art and would be strictly a fansite and as a non profit site. Would I be able to do this and not be conflicting copyright laws, as I do see lots of fansites u afbeeldingen from populair cartoons. Thank you, also would anyone here be willing to play it? thank u :)
