Popehippo on WoW Ladies LJ was kind enough to post these 59 icons, directly from the World of Warcraft comic. They actually come from all over the place, including the comic itself, as well as from cover and concept art. And there's all kinds of different stuff in here, from Orcs to dragons to Druids to Naga.
They're meant, of course, to be used on Livejournal, but they work, I'd imagine, for all kinds of icons, from Twitter and IM to even the comment profiles right here on this very site. If you've been poking around for a Warcraft-themed online identity, look no further, odds are that there's a cool piece of art you'll find in this big layout Popehippo's assembled.
