I’ve just completed the random background tutorial (thanks for making it so easy to follow!)
My questions are:
1. Is there a way to alter the code so it’s not random, but instead follows a preset list of images? So, instead of pressing a button and randomly choosing from the 5 images, it would go through the list starting with image0
2. Is there a way to preload the first image so it shows up when the viewer goes to the main page (where the background changes first occur)?
3. If someone goes to a new scene within the larger movie, would I have to place the same code and button on every page and the viewer would have to load the background image every time?
Thanks in advance!

```auto
choice = Math.round(Math.random()*5);
switch (choice) {
case 0 :
location.loadMovie("image0.swf");
break;
case 1 :
location.loadMovie("image1.swf");
break;
case 2 :
location.loadMovie("image2.swf");
break;
case 3 :
location.loadMovie("image3.swf");
break;
case 4 :
location.loadMovie("image4.swf");
break;
case 5 :
location.loadMovie("image5.swf");
break;
}
```
I would do something like
```auto
choice = Number
```
See if that works. My AS level is medium but I don’t know anything about switch case stuff.
