Load a different image to stage

Question

Hi there,
I am trying to place an image on the homepage of a website i
am building but i want the image to change every time the page
loads. could anyone give me an idea on how to set this up or know
of a good tutorial? my client is a photographer so they want to
display a different photo every time the page reloads. i also want
the anchor point of the image to be at the top left so the image
begins at the same place. Any ideas? thanks in advance.

Sure. The basic idea is simple. You want to load a random
image. Flash only provides one means of generating anything random
and it's the random() method of the Math class.
By itself, random() is only going to help you generate a
number. But if you take it one step further and append that number
result to ".jpg", what you'll get is a String pointing to the
filename of an image in this case 1.jpg. For instance
// Math.random() returns a 1 stored in a variable named pic
var myFile:String = pic + ".jpg";
Now you can use loadMovie, MovieClipLoader (both AS2) or the
Loader class (AS3) to load the file onto the stage. I'll show
MovieClipLoader and Loader
// MovieClipLoader - assumes images loading are in same
directory as swf
var myMCL:MovieClipLoader = new MovieClipLoader();
myMCL.loadClip( myFile );
// Loader - assumes same as above
var _ldr:Loader = new Loader();
addChild( _ldr );
_ldr.load( new URLRequest( myFile ) );
The only code you need to control is the Math.random() so
that you put an upper and lower bound on the returned result. You
can find help with that inside the Flash documentation.
Hope this helps.
