The two 101 pages (both general and adult side) link to this image:

However, the image doesn't exist under that name.
Other than that, I've trundled through both the archives completely, and all the links at the bottom of the comic (the first, previous, next, and latest links) are accurate. I didn't check the side links, nor the links at the very bottom, and on every page, the hit counter at the bottom was broken.
Oh, and in passing, I noticed some comment about not knowing how to set up a favicon; favicon's are done by putting a file labelled favicon.ico in /, and, optionally, some code into the html: See for details... Basically, it's just an icon, so 16x16 and whatever else you need to make the format happy. I -think- Photoshop will save directly to icon. I'm pretty sure The Gimp does, so should be ok. Failing that, a quick google will link you to half a dozen converters. ;-]
