Problem w/ coroflot.com portfolio thumbs. Help?

I know the reason is probably so obvious that I’m gonna smack my forehead and exclaim, “Doh!” in my best Homer Simpson voice after you all tell me, but how do I get my thumbnail images to look as clean as the full-size ones?

Thanks

Make sure your JPEG quality doesn’t go below 9 or so when saving, that should take care of it…
