Since I don't use Mac OS any more I won't be updating this Xtra, but it's fairly simple to do yourself.

Here's how:
1. Use the Download link above to get the .AdiumEmoticonset file
2. Right-click the file and choose Open Package Contents to open it up as a folder
3. Copy any additional image files you want to use as smileys/emoticons into the folder
4. Edit Emoticons.plist with a text editor (TextEdit works fine) and add definitions for the new emoticons. This is basically an XML file, I'm sure you can figure out how to edit it properly.
5. Install your modified version of the package by double-clicking the .AdiumEmoticonset file

Glad you loke it!

Feel free to use the heart! The whole set is released into the Public Domain so feel free to modify and repackage it in any way you'd like. You don't even have to credit me and you can even sell it (althought that'd be a bit questionable). :) Good luck with your set! ^^

Thank you. :)

I'd recommend editing another Xtra. Basically the smiley file is a folder. You can open the contents by right-clicking it and choosing "Show Package Contents". Then you can replace the images and edit the definitions in the XML file inside. Play around.
