Anyone have a javascript that will allow me to change the state of two graphics when you roll over one of them? I want to have buttons that change, and then a different image that explains each one. Can anyone help?

Yeah, DocOzone's script is perfect for this. It's an amazingly simple yet powerful script, so it might take a minute to wrap your brain around if you're not familiar with programming concepts.

The one in the handson section?

Can you tell me how to get that to do multiple switches?

Also, I need the second graphic to chagne into 4 different ones.

Okay if you have Docs script doing the rollovers then you can add a couple of lines to do this. Here is one way:
<SCRIPT LANGUAGE="JavaScript">
<!--DocOzone's Javascript code, copyright 1998
// Feel free to borrow and modify this code,
// but be sure leave this credit in the source!
// Your pal, -Dr. Thaddeus Ozone-
// .http://www.ozones.com/

window.onerror=null;
// that was to turn off error reporting...

if (document.images) {

/* Okay we need to preload our images for the over states of the single image we are going to change. You said there was 4 states so we are going with that
*/
imageover = new Array();
for (j=0;j<=4;j++){
imageover[j] = new Image();
}

// Now we need our 5 images (1 defualt and the 4 over states

imageover[1].src = '/default.gif'
imageover[2].src = '/over1.gif'
imageover[3].src = '/over2.gif'
imageover[4].src = '/over3.gif'
imageover[5].src = '/over4.gif'
names = new Array( "zero" , "one" );
buttons = new Array(4);

for (m=0; m<=7; m++) {
buttons[m] = new Image(); }
buttons[0].src = "zeroA.jpg";
buttons[1].src = "oneA.jpg";
buttons[2].src = "zeroB.jpg";
buttons[3].src = "oneB.jpg"; }

// now we change this to do 2 things at once
function swap(des,num,mainNum) {
if (document.images) {
document.images[names[des]].src = buttons[num].src;
// add the if statement so this doesn't cause anyproblems if used elsewhere
if (mainNum) {document.main.src = imageover[mainNum].src}
}}

// close the comment tag, this hides the script from really old browsers! -->
</SCRIPT>

Okay now when you write your links they should look like this:
<a href="http://www.handson.nu" onMouseover="swap(0,1,1)" onMouseout="swap(0,0,0)">

where the third number is the number of the image you want the main to be. (0 = defualt, 1 = over1, 2=over2 etc).

Lemme know if you have questions

Yup it's the name of the image you want to change. I hard coded the name of the image into the swap function (soory should have mentioned it). so there is the line that looks like this:
if (mainNum) {document.main.src = imageover[mainNum].src}

You need to change "main" to the name of the image you want to change. remember all the images you want to swap must have a name otherwise the script doesn't know what image to change. I think (not sure but it looks right) the image you want to change is 1-1-0.jpg? you can either actually name this "main" or name it whatever you want and then change the function to reflect that.

cool?

So, I replace every instance of main with 2-1-0.jpg? That's the image being changed. The buttons then also chagne, which isn't working either.

Not quite, its not the actual name of the image (2-1-0.jpg) you need to name the images in your image tags. Like this:
<IMG SRC="2-1-0.jpg" NAME="MAIN">
