Miko Lee pic source edit
Have you tried Flickr? Use the Advanced search to look for any pictures that are licensed using Creative Commons, but make sure that it does not have the No Commercial and No Derivitives tag! Also, watch out for copyvios... things like Miko Lee wallpapers with the Commons tag where the original picture is almost certainly copyrighted.
There are other source... check in the WP:P* article for the listing of where you can go. Tabercil 19:42, 17 January 2007 (UTC)
