Haloscan Emoticons

I want to add some more emoticons to Haloscan but all the Haloscan forums seem to offer is a solution to replace the existing emoticons by replacing the images using Javascript. I know how to add support for more emoticons into Haloscan but I am rubbish at Javascript so I can't code it myself.

If anyone out there is a bit of a dab hand with Javascript and has a spare 10 minutes on their hands, perhaps they'd like to volunteer to write a short script?
