Oh, don't worry! I will! (if I like something the poor souls on my f-list are doomed to be subjected to it, ha ha!)

Really? I have GIMP 2, is that what you have? But when I'm working on an icon, I flatten it (which you have to do unless you're saving it as a .xcf layer file) and then click Save As and where it says Name: just type in whatever, e.g. "northandsouth_margaret_smile.png" but without the quotation marks. Is GIMP not saving them as PNGs or is your hosting site rejecting them?

Now I am very anxiously looking forward to your next batch! :-D
