Replace an image with another when a different image is hovered on

Question

I am a total noob, so please go easy.

I am trying to replace one image with a second image while hovering on a different element. My problem is that only the first image is being replaced by the link images. I've give each image an ID, I just am not sure how to apply it.

Thank you in advance for any help you can provide!

Here is what I have so far:

Script:

<script>

function changeimage(towhat,url){
if (document.images){
document.images.targetimage.src=towhat.src
gotolink=url
}
}
function warp(){
window.location=gotolink
}

</script>
<script language="JavaScript1.1">
var myimages=new Array()
var gotolink="#"

function preloadimages(){
for (i=0;i<preloadimages.arguments.length;i++){
myimages[i]=new Image()
myimages[i].src=preloadimages.arguments[i]
}
}


preloadimages("http://www.dxmgp.com/group/images/color_si.jpg", "http://www.dxmgp.com/group/images/bw_si.jpg","http://www.dxmgp.com/group/images/color_dxm.jpg", "http://www.dxmgp.com/group/images/bw_dxm.jpg","http://www.dxmgp.com/group/images/color_tsg.jpg", "http://www.dxmgp.com/group/images/bw_tsg.jpg","http://www.dxmgp.com/group/images/color_image.jpg", "http://www.dxmgp.com/group/images/bw_image.jpg")
</script>

HTML:

<div id="wrap">
    <div id="upper">
        <div class="u-top">
            <a href="javascript:warp()"><img src="http://www.dxmgp.com/group/images/bw_si.jpg" name="targetimage" id="si" border="0" /></a>
            <a href="javascript:warp()"><img class="picright" src="http://www.dxmgp.com/group/images/bw_dxm.jpg" name="targetimage" id="dxm" border="0" /></a>

Answer 1

How about something like this? Consider you have a div containing image1.png. When you mouse over a hyperlink, you want to replace image1.png with image2.png. Then, when you move your mouse away from the hyperlink, image2.png will once again be replaced with image1.png:

This is your div containing the image:

<div id="image">
<img src="image1.png" />
</div>

This is the hyperlink:

<a href="#" onmouseover="mouseOver()" onmouseout="mouseOut()">Mouse over to change image</a>

Here are the JavaScript functions that will replace the inner HTML of the div with different images:

<script type="text/javascript">
function mouseOver() {
    document.getElementById("image").innerHTML = '<img src="image2.png" />';
}
function mouseOut() {
    document.getElementById("image").innerHTML = '<img src="image1.png" />';
}
</script>

Let me know if this is what you are looking for.
