"A Must-Have program."
It can import almost any image file and create up-to-date icons, even with transparent backgrounds. And, now that I've figured out how to output png files for Linux purposes, it seems like it does everything a person could possibly want.
It isn't made for Linux.
I've spent many happy hours designing 32x32 icons in Goldshell's formerly free icon editor and wishing I could work with some of the higher resolution icons.
IcoFX is like a dream come true. There is a small learning curve, but the online help pages are actually helpful and I'm sure that this will become an essential part of any developer's toolkit.
