Thanks to a few readers’ suggestions, I stripped the gamma information out of the PNG files, and now they look spiffy, even in IE. I’ve also been informed of a few server-side fixes that would make PNG alpha transparency work, but I’m going to shy away from that for now. No need to overtax the server. Anyhow, by stripping out the gamma info and crushing the PNGs as much as possible, the total image data count for the front page goes from 53kb to 37kb (not couting the comic and various ads, of course). That’s not too shabby at all. :) Thanks for the suggestions, guys.
