Make the Image Stay

Here is the Code:

function linksfun() {
document.sitelayout_17.src="images/sitelayout_17-links_over.gif";
}





<A HREF="links.htm" onClick="linksfun();">


I want that image to stay displayed until another onclick changes it. I'm not real good with JavaScript and I thought that maybe using the return thing would work but it didn't. How would i go about doing this?

So you want the image to change when clicked.
Call your function, determine what the current filename is (imagename.src property), then, if it's the on-state image, set the src to be the off state, and vice versa.
