FXPaint is ok from what I have used of it in the past (v1.5) although its interface does seem to be a bit back to front for my liking (can never work out how to do a particular effect in it! :-/ ), However, I do like its nifty little html image slideshow thingymebob creator facility. That looks to have been improved in v2 also.
For me though, I have got to give my vote to the excellent ArtEffect v4. Its features have given me the ability to do the things I have wanted to be able to do in many other programs but been unable to work out. Unlimited layers and undos and reasonably quick too mean its definately the program of choice for me :-) (used on both of my websites listed below)
:-D
