"img" is the name assigned at the end of the following tag:

<img src="http://www.denijsdesig n.de/dd_images/i_allg/xtrans_x_320x32 0.gif"
border="0" width="320" height="320" alt="" name="img">

Yes, but you try to access it using getElementByID, which is looking for
an *ID*. The fact it works in IE only means IE is getting it wrong.

No, its a version that works in IE, and no other browser I tested it in.

The javascript:, AFAIK, is not needed there.

Here, you are trying to access an image with the name="img", yet the img
tag has no ID attribute, hence it fails in non-IE browsers. This is but
one error code produced by Mozilla:

Error: document.getEle mentById("img") has no properties

Try this though I only tested it under IE.

var form = document.fruitf orm;

if (form.elements[i].value != "0") {
if (form.elements[i].name != what) {
form.elements[i].checked = false;
}
}
} else {
if (form.elements[i].value == "0") {
form.elements[i].checked = false;
}
}
}
}
}
</script>

Don't include signatures when quoting someone else's post. A good

You missed my point entirely. You identify that element by name, yet you
use the getElementById method. Surely, common sense tells you something is
wrong with that.

I've mentioned before that using getElementById should only be used when
appropriate collections are not available. In this case, use the
document.images collection. It will retrieve images identified by both id
and name (ids checked first).

It pays you to test everything in a decent browser, rather than IE. Once
things are fine in Opera and Mozilla, then check with IE.

There's no problem here, but if the swapped-in image is important, make
sure it can be accessed even if Javascript is disabled. The easiest way to
assure this is to place the images within links.

function replaceImage(fN , iN) {
document.images[iN].src = fN;
}

<a href="first-large.jpg"
onmouseover="re placeImage(this .href,'mainImg' );">
<img src="first.jpg" alt=""></a>

<a href="second-large.jpg"
onmouseover="re placeImage(this .href,'mainImg' );">
<img src="second.jpg " alt=""></a>

<a href="third-large.jpg"
onmouseover="re placeImage(this .href,'mainImg' );">
<img src="third.jpg" alt=""></a>

<img name="mainImg" id="mainImg" src="first-large.jpg" alt="">

Can you show the structure of this particular section of HTML? It might be
usable as is, or you might need to restructure it.

You are fortunate. I said, "Mouse-over" once and got taken of with VB6.0
and eventually, I am swimming on events with VB.Net Whidbey with
additional support thrown in in the form of DHTML.

Have you heard of RollOvers?

Hi Mike.

Just in case you still see this and are willing to help, I've made a
(very) quick and (very) dirty example page kinda explaining what I need..

faceman.com

I'll keep hunting, but any help is still appreciated. :)

Thanks again,

The following is how i did it. I used Macromedia's canned js image
rollover scripts allong with my own for changing the text attributes
and CSS (or script) attributes for the text. Makes it easier to play
with how you want to change the text. You'll need to create the
images circled.gif and rectangled.gif for the rollovers...

Will this do, at least as a starting point?

<URL:http://www.mlwinter.pw p.blueyonder.co .uk/clj/makela/mouseover.html>

Notice that I haven't used your image filenames. My rollover script
depends on a pattern existing in the filenames for it to identify images
that it should interact with. Whilst it doesn't have to be <name>-on and
<name>-off, it does need to be something similar.

Hope that helps,
Mike

Sorry for the delay.
