*looks at username*
Anyway, without me going into the various sarcastic comments I could apply to your username in this situation, and believe me, there are a lot - I'm a twisted individual - um, where was I? :p
You need to save the textures for your skin as baseline JPGs, not progressive JPGs.
If you're not sure what I mean, [color=lime]this thread[/color] asks a similar question, and has it answered in more depth.
(There are some issues with images on the forum lately, you might not be able to see them, so if you can't see them, post again and I'll repost the images.)
I don't know how, and I don't know why, but this is totally Sheep's fault.
