Loading a different image each time using LSOs
Minimum Flash version:
CS3
ActionScript version:
3.0
Accompanying thread:

What you'll learn:
You'll learn how to keep track of data from one visit to another using Local Shared Objects (LSO).
You'll also learn how to generate a random number to load images randomly.
Scenarios:
- You have N images, and you want to show a different one every time the user comes to your website.
- You have N images, and you want to show a random one, which is different from the one shown on the previous visit.
Other common scenarios are:
- You have a music player and your preferences for mute, replay and shuffle or are remembered.
- The first time you visit a site you see an animation playing, but the next time you don't.
Solution:
In order to keep track of data from one visit to the other, Flash offers Local Shared Objects. These are "Flash cookies" that let you store data in them.
The next time you visit the site existing data that has been stored previously can be retrieved and used.
The obvious solutions for scenarios 1 and 2 are pretty much the same: keep track of the latest image.
For 2, this could be done by using its path. For 1, it can be its position in an array.
I'm going to use an array and the position for both.
