I think Walrus once described bloggers as "the biker gang of the net."
Silly little things like copyrights and ownership seem beneath a lot of bloggers.
As for funny stuff, I have a friend who often surfs the web in search of akward expressions of Mr. George W. Needless to say, it doesn't take much effort.
I believe published photos of public figures can be cited as long as you reference the source... maybe someone with copyright expertise could advice you on that one.
Wish I could help you with a "legal" source, but I don't know any. Sorry I could only be the voice of a pirate.... Arrrrgh!!!
Um... yeah.
