Flash is a 2D animation software widely used in web and in presentations. Flash CS4 is the recent update of this software. Flash software is so simple that animation can be done in ease. There are two important thing in flash, timeline and method of animation. There types of animations. Animation done fame by fame is called fame by frame animation. Tween animation is the one where we use motion tween and shape tween. Flash is a vector software. So it's easy to import the illustrations done in Illustrator CS4. It's better to not to group all parts of illustration. For example, If we have an illustration of man don't group him entirely, hands, legs etc should be separate so it would be easy to do animations in flash.
