InsaneJournal Announcements

You can get up to 400 by adding "extra userpics - 12/6 months" to a regular paid account, I believe, and up to 500 by adding "permanent extra user pics" to a permanent account. There's also a 5,000 icons deal for, like, $75-100 or something, called "insane userpics" or the like, but I'm not sure if that's offered all the time. It's not available right now.
