Turning platformer character sheets into 4 directional?

I have a bunch of platformer character sheets and wanting to use those characters in a top down dungeon crawler type game but need to be able to have movement for up and down as well as attack in up and down positions. Is there any good software programs that make it easy to do that kind of thing? If not anyone know of some people/sites that will do this at a decent price?

I assume that the graphic is drawn from the side. If so, then I don't think there is a way you can covert them into the Top-Down angle you want.

Reuben ok thanks. I thought that may be the case but you never know what's out there and thought I'd check
