Besides, to
help you organizing all the elements of a graphic, Flash works with layers. Each layer contains a
different element from the same frame (layers from the same frame are shown
together, fig. 2). Besides, you must
use a different layer for every object if you want to animate these objects
(important!). You can lock and hide each layer independently to work better, as
well as name them and organize them in folders.

Another basic
concept of Flash are symbols.
A symbol can be just an image (“graphic”), an animated image (“movie clip”) or
a button. However, not every image you draw is a symbol: you must convert it
(fig. 4). Symbols are useful for two reasons: first, because they are better
for animating images, and second, because you can reuse the same symbol as much
as you want without making your file heavier. Every time you use a symbol you
work on an “instance” of it, which you can edit without modifying the original
symbol (fig. 5).
