Turn a solid image into just an outline?
Hello, I have a simple question that is driving me crazy. I have a guitar pick jpeg that is a black pen line filled with white I am using for a design. I placed the pick image into Ai and now can't figure out how to change it. I just want to select the image, and transform it into just an outline of the pick, all transparent everywhere except the outline shape of the pick. Almost the same as if I had drawn the pick with the pen tool, but I don't want to have to draw it. My skills in that are beginner and not very good to say the least.
Thanks
