Because I was getting tired of the default Seamonkey icons, I set about converting a couple iconpacks which I found on iconpacks.mozdev.org.

The iconpack xpi files are just zip files, so I unpacked them and converted to os2 icon format. I think the icons look ok, but if anyone knows a better way to convert from windows format to OS/2-ECS drop me a line. The orginal xpi javascript just copies the icons to chrome\icons\default, so I just use it rather than make changes. Once complete I just zip everything up and place it here. I also include the default icons if, for some unknown reason, you would want to revert.
