The program is very stable and reliable. Documentation is above average. A fat glossy manual was produced for release 2.0, with lots of illustrations and examples. Additional features for 2.6 are documented in a 46-page addendum, which could use some expansion. Overall, however, the documentation is well done.
Technical support is excellent.
Try to find that in a PC or Mac software company. Tech support is also available by FAX and online through Portal, Compuserve, and Genie. There is an active mailing list which serves as a forum for users to share tips and ideas. The problem, of course, is that a program like ImageFX is so incredibly complex. Nova Design has chosen to provide the user with almost complete control over every effect, and has still done a pretty good job of streamlining the interface.
