Yeah, mines Illus 8, saved as eps. Thought it might be handier than native Illus file (or does everyone have it already?)
I've found a good way of making vector art from b/w eps files, if any one is interested?
Using Illus CS, import the jpeg you want, use the live trace tool and copy the file.
Bring the values up a bit (or down, it all depends), and use the preview to see if it's what you want.
Make a new Illus file, paste and use the fill to fill with whatever color you want.
It's an awful lot quicker than trying to trace by hand.

I haven't tried it yet with a color image, might have a go later.
