The above post is good, but i do it a different way, unless your terminology is just different than mine haha.Anyway here goes:1. Start out by making the button.2. Convert it to a button symbol. 3. Double click on the button, which opens up a whole new set of keyframes.4. insert a keyframe in frames 1 and 2. Frame one is the button at rest. Frame 2 is the mouse over frame. Frame 3 is the when the button is pressed down. Frame 4 is called the hit frame, meaning whatever you put in that frame is the invisble outline of your button, so the computer knows where the button is.5. Ok on frame 2, insert your robotic picture and place it where your want it in relation to the button, it can replace the button if you like.6. when your done and satisfied, double-click the mouse away from the button to get out of the edit mode, then do a test movie and see if that worked out
