Animating Imported Images When animating an image that you import, you need to separate the sections to be animated because Flash cannot distinguish objects like arms and legs. Let’s make a jogger raise his arm and wave. A jogger has been prepared for you and his arm will need to be separated into 3 sections, biceps, forearm and hand, then the 3 sections will be linked using the BONE TOOL
