Trace bitmap is better for images with lots of solid color and little to no shading. I tried tracing a 138k jpg of a colored pencil drawing I did and came back with a 5mb vector image... The best option is to import them as png's and set Flash to save them internally as jpgs. Then tweak around with the compression levels till you get what you want. I use png if I want some transparancy. Like if I'm importing a Possette http://www.atless.net/~arcady/flash_work/gallery.html for example. (done for a school assignment, don't bug me on the bad design please. :) ) Otherwise do the jpg compression in photoshop/psp/fireworks before importing. Or import a bmp (or PICT for Mac people). Flash can only import eps images from Illustrator 6 or less (and sometimes 7). So check how PSP is saving them... For the best non-flash vector results you want Freehand. Flash and Freehand are somewhat 'tweaked' to work together well.

Truth has no value without backing by unfounded belief.
