You must have at least two objects.  This also means that you have two layers.  Each object is on a layer by itself.

If you are using a picture, the picture must be imported into the library 1st.

To create a moving object:
1.  Size the stage if necessary
2.  Select frame 1 and place or draw an object/text on your stage.  Move the object to where you want it to start.
3.  Right click on frame 1.
4.  Create a motion tween.
5.  Click on frame 48 and insert a key frame (F6).
6.  With frame 48 selected, move the object to where you want it to stop.
7.  You must add rotation and or ease to your object.
8.  Create a new layer and rename it.
9.  Start over at step 1.

To Stop the flash from moving:
1.  Select the last frame of one of the layers
2.  Go to the Actions-Frame panel
3.  Action > Movie Control > double click Stop
