I've posted a few, but that was a over a year ago. I prefer to just post icons that I make now.

Used to, not any more.
I know a lot of graphic makers are getting really pissed about people reposting their stuff here, so yeah, I just post my own stuff now.

I rarely do that. I think I did it once not too long ago but that was the only time I did if I'm not mistaken. I do post icons that I make.

I don't think so :P

I still do it. I'm not good at making icons at all, and other people do it. Besides, I in general give credit. So I guess that's okay.

I prefer to submit my own.

I post pictures from livejournal, but I always give credit.

I used to but not anymore. I've heard that they can be pretty anal about it. So I'm not gonna risk it. There was one LJ user who asked me to remove the ones I had put up, but he/she was nice about it so it's all good. But the ones I took down for him/her were the only LJ icons I uploaded. So nope.
