Help with "Emoticons"

Currently the Chat-System uses generalized emoticons instead of the cacomoticons we have on the forum and guestbook. I am a bit limited in time currently and my pixel-drawing-skills aren't the best either but I'd be happy if someone could give me a hand with replacing the original "JChat" emoticons with the new "Cacomoticons". I have attached two zips, one with the originals, one with our replacements (which are actually missing a few replacements).

Thanks already in return for your help

*EDIT*
I love making my own threads sticky...

Yes, I know, bumbing a sticky makes a lot of sense, but isn't there anyone who's capable of helping here?
