Where is it stored?...I remember using iChat for the first time and it just placed my current icon, that, i thought I lost in the first place! Weird...
i have no idea where ichat stores your icon. but you can just click on the icon box on your buddy list and paste any image in, and resize it accordingly🙂
I've had trouble making this work; for some screen names, iChat insists on using whatever icon it first used. iChat for me has been, on the whole, unreliable.
