OnMouseOver and image maps working across multiple images

[seegoon]

Hi all.

So: I've put together a page, in which I want several clickable image maps. I've put those together already. The problem with image maps is that they're not very intuitive, so users don't really expect the image to be clickable and accordingly won't even try to. The solution is to have the image highlight whenever the mouse travels over the mapped-out area; I understand that this is quite easy. Some Googling has provided a few solutions.

However, my problem is this: because of the way the page was designed, some of the images themselves are split into separate jpegs; they were sliced up by the designer in Photoshop. What I need your help with is ascertaining whether it's possible to have one mouseover highlight two jpegs. To illustrate, one of the images is of a pig, foal, lamb and chick, with each one image mapped already. To get the required effect I understand that I can create four new images: one with each animal highlighted. Then I can get the image map to show the highlighted version with a tiny bit of scripting. But the pig's ear is cut off, and sits in a different jpeg. Could a mouseover of the 'pig map' in the large jpeg also prompt the ear - a different jpeg entirely - to change as well?

I'm not explaining this very well, I have to admit, but in principle it seems simple. If you need any further explanation I'll be sure to give it another go.

Thanks for reading regardless. If you got this far.

it is possible ... of course ... could you please post en example of the code you already have ... so that we have something to work with?

kind regards

I’d try to change the mouse pointer shape (hand), so that is represents a link.

@Dormilich
It seems to do that anyway. But I think the problem still remains - it's not obvious enough in my eyes.

Here's a really stripped-down version of what I have at the moment, which should give a good impression. It works, but only on the one jpeg instead of across two.

Here's the Javascript in the header:

<script language="javascript">
 
Image1 = new Image(232,275)
Image1.src = "images/hostage-cover.jpg"
 
Image2 = new Image(232,275)
Image2.src = "images/hostage-cover-highlighted.jpg"
 
function highlight() {
document.hostage.src = Image2.src; return true;
}
 
function original() {
document.hostage.src = Image1.src; return true;
}
 
</script>
 

Here's the code for the image:

<img 
name="hostage" 
src="images/hostage-cover.jpg" 
width="232" 
height="275" 
alt="Hostage cover" 
usemap="#hostage"/>
 

And here's the image map code:

<map name="hostage" id="hostage">
 
<area    
shape="poly"
    coords="2,34,26,273,255,254,201,14"
    href="http://books.mileskelly.net/menu1_sub1_detail.asp?ID=657"
    title="Click here to find out more about Hostage"
    onMouseOver="highlight()"
    onMouseOut="original()"/>
 
</map>
 

In case you're worried, Hostage is a novel! If there is any wasted code here, then please let me know and I'll glady destroy it.

Basically, what I want is for that mouseover to highlight two images instead of just one.

Thanks!

@seegoon
then you need to treat two images in the highlight() code.

@Dormilich
Sorry, I don't understand. Do you mean add another image to the highlight() in the script in the header? Thanks.

[Dormilich]

@seegoon
yupp, that’s what I’m talking about.

@Dormilich
I've tried but I'm not getting it right. How should the code look? Thanks.

function highlight()
{
    img1.src = "picture1.jpeg";
    img2.src = "picture2.jpeg";
}
