Sorry, but you'll have to redraw the picture in a vector graphics
program (Flash, Freehand, Illustrator) making sure only to use vector
tools. Motion blurs aren't *really* possible in vector graphics, but
there are ways of approximating them.

You are right that it improved speed, particularly download speed as
vector graphics eat less bandwidth. But you'll need different tools
to create and modify them.

Vector images are made of mathmatically determined lines (vectors)
while bitmap images are made of pixels. Vector graphics are
infinitely scalable - but they don't have the ability to look like
photographic images.

If you make the artwork in Flash, it will normally remain vector.
