yep.. somebody ported AGI Studio to Linux which was a bit of a big project cause they converted it all to C++ and QT. Then Nat Budin ported it to Windows (hence the Windows Linux AGI Studio).
The only problem is QT. They make this big hoo-hah about it being opensource but it's only GPL in the Linux environment. If you want to use it in Windows, you need to use a crappy VC++ only free version or pay money for the commercial library.
Anyway.. the picedit's fairly slow in the Windows version I tried. it's still available on my site if you want to try it.
