I'd like to point out that width=1000 should be acceptable. I don't think there's anyone who seriously still surfs on 1024x768.
and keep in mind mobiles.
1000 wide images cause me to page stretch, 800 hits the edges exactly.i use safari on an ipod.
that image with a girl about to get raped by a dinosaur and an elephant in Skyrim is 1024px wide
