It depends a little on the drawing. Maybe you have to smooth it before you try to put it into vectors. Inside Photoshop you can turn a selection into a path. So you could try to experiment with the magic wand, to select your black lines, and then goto the paths tab, and then make a path. If your drawing has more than one color you should do this color by color, saving your paths by doubleclicking them. If you have PS6 you can do the vector stuff in layers instead of fussing around in the paths section. By the way, Flash also does some nice tracing (and I vaguely remember the Poser ProPack can render external bitmaps to Flash vectors, which can be converted to Ilustrator, which can be pasted into Photoshop. Mmmmm, sounds like it is cheaper to buy Streamline then). If your drawing is a simple line drawing, you could use it as a template and make it into a vector graphic by hand. If you really can't work it out, you may send me a hi-res jpg (low compression) by email and I will run it through Streamline for you and mail a vector eps back.
