Well as Yahoo is going to sut down their photo service, they moved all mine to flickr. Now I had a quick look around at first and thought hmmm yeah there are some good pics here, well they put mine to shame LOL.
Then I had to do it, search for naughty stuff. Oh yes its there! Well I found one collection where the owner has ripped pics from different sites. Now the groups area can provide some surprising results :D
Just try it and see what you can come up with.
