Compfight, which is unarguably the best tool around for searching photos on Flickr, just got a makeover. Other than a slightly revamped search interface, the most useful addition to Compfight is the ability to bookmark photo search pages.
So if you are looking for Vista wallpapers on Flickr that are shared under a Creative Commons license, all you have to do is put this address in your bookmarks.
The only missing option is size search – so you have no way to pull photos from Flickr that match a particular dimension. Thanks Sarah.
