I do basically steal pictures for this site on occasion. Usually I try to link to wherever they came from, though sometimes I really can't be bothered. Anywho, I don't do legal mumbo jumbo, but if you've an issue with a picture I have up email me at email@example.com with proof of copyright or licencing or whatever and I'll take it down happily.
Title your mail: 'I'm a Meany Mean Person', as I've set up a filter for this title so they won't accidently end up in my spam folder. Also make sure your email looks right, I won't take pictures down for a firstname.lastname@example.org or anyone I suspect of being just a troll.
I hope that's all clear.
