This tutorial is about the use of flash mask effect to make nice picture switching effect. This tutorial uses the simplest of the flash masks as an example, and of course you can use your imagination to make more and better picture animations. I hope this tutorial will bring you some help.

Let's look at the effect first:

First, open flash create 1 new layers, draw a vertical line with the line tool, place the left side of the relative stage, and insert the keyframe at frame 30th.
