Once you have everything set you can then create your image, or what ever you want on the stage by either using the tools on the left hand side, or by inserting a previously created image.

Now that you have created and setup your Flash Document, you can start with your animation.

First place your image on the screen, which is called the stage.

Then your going to want to select the Timeline. Below is an image of the Timeline in Flash MX

In the Timeline you will notice that there are layers. You can add layers by hitting the button. You can delete layers by hitting the Trashcan in the bottom right.

The boxes with a circle in them mean there there is an empty frame. Flash works in Frames, just like if you had a old booklet with a bunch of images in them and if you go through them really fast it will look like a cartoon animation. When you put something on stage the white box with a circle turns solid with a solid black circle, that just means that there is an inanimate object on the stage.
