in Macromedia flash there are many ways to make animations. the easiest one is probably to draw something on the stage, click on the next frame and hit F6 or right-click on it and click insert key-frame, then on that frame move the image a little, then repeat. depending on what you are trying to do there are different ways to move things, so I recommend going to https://www.kirupa.com/. it has a lot of really good free tutorials.
