Almost no sites- this one is no exception - are going to let their necks be on the line by letting their members upload copyrighted images to their accounts. Wikipedia admins, if they come across copyrighted images (or images whose copyright status isn't "tagged" by the uploading user) (and others - one didn't have to be an admin to do this) are encouraged to leave a - polite - note in the talk section of the user's page asking them to clear this up; and if it goes further than this, Wikipedia has a tutorial clearing up copyright issues, general and detailed, to help people decide whether or not something is a problem (and so should, better safe than sorry, be removed). The tutorial, anyway, is here --

This is me speaking, not a bouncer, and not passing on anything written by Scrapper or Baby Jesus, and definitely what holds for Wikipedia has to be modified somewhat before it applies here; but all those images of your favorite screen idols, anyway, you may want to consider whether they're really copyright-ok, hrm? Promotional posters are more likely fine - because they _are_ promotional posters. That by way of example...
