Thanks a bunch guys
I have a cable modem, and I went right ahead and downloaded PSP8 and sliced, and everything worked great. I couldn't find the slicer in fireworks.
The fireworks slicer is a bit harder to use.
Because in PSP8 I could click on the X and it slices it itself to same sized shapes. and that's exactly what I needed.
The fireworks slicer is a bit harder to figure out, but you can slice a lot better with it (if you need to) so I'm going to keep both.
