I look at other people's profiles, and they have a ton of images up. I look at mine, and I see a scant handful.
It's not that I don't have enough to put up - hell, there's something like 3500 up on my website! I only have a few up so as to not bore everyone. I have a few up on here that aren't even up on my website. I dunno, maybe I'm just picky.
