Yes, I know he didn't wan't the hassle of converting them...
However Gfx-Con is one of the most "hassle-free" options.
Like " I'll pmail you if I have it.." , or "I'm not sure about the saving part",
probably weren't the direct answers he'd like.
Gfx-Con can be applied to many other situations, and it's a direct dl.
I also recall some sort of datatype loader-/saver on aminet for DP,
but instead of "maybe" or "perhaps", mine is an answer that will work directly.
There are other apps like Photogenics (v5+) and ImageFX that do batch-conversions... And then there's quite a few pc-options too!
Best Regards!
