being an OS-legal application, if written in C or C++ might be ported in other amiga os flavors; did you tried to contact the developers about it? if not will try to send a mail...

I think it would be fantastic if Image Studio (and their later software Draw Studio) was ported to MorphOS, Aros and OS4, but I don't think I'm the right person to try and contact the authors about it to ask for the source, I'm too shy and socially retarded. I think someone like Gulliver might have a better chance since he has more experience and has done a great job so far with other software.
It's also possible that a lot of the image processing routines were written in Assembly and might not be portable.
Sorry, I don't want to seem negative but it's been a pretty sad time lately.
