Anybody see why this is not working!

Hi, I cliped this and mofified it to be used in a mouse_over to change
the background of text. This is supposed to pre-load the image on
mouse over but it don't!

<script language="Javascript">

function ImgPreLoad()
{
var my_images_array = new Array ('ltrhome.jpg', 'ltrabout',
ltrphoto.jpg', 'ltrmap.jpg', 'ltreq.jpg', 'ltcont.jpg');
LoadmUp (my_images);

}

function LoadmUp (my_images_array)
{
for (loop = 0; loop < my_images_array.length; loop++)
{
var one_image = new Image();
one_image.src = my_images_array[loop];
}
}

</script>

You cliped [?] from last century, nowadays use:
<script type='text/javascript'>

> ltrphoto.jpg', 'ltrmap.jpg', 'ltreq.jpg', 'ltcont.jpg');

ltrabout? that an image name?

You do not need a function to decalre an array.

> LoadmUp (my_images);

Unknown parameter my_images

Never reuse a variable name a a parameter, You will make mistakes.

Now my_images_array is not an array but ponts to the undeclared variable
named my_images. That should give an error!

(var loop = ....

my_images_array.length: undeclared variables have no length.

> one_image.src = my_images_array[loop];

not an array.

You do not need a function for preloading.

The reason you get no error could be
that you do not call ImgPreLoad().

===========================================

Try:

<script type='text/javascript'>
var oneImage;
var myImagesArray = ['ltrhome.jpg','ltrabout.gif','ltrphoto.jpg'];
for (var i = 0; i < myImagesArray.length; i++) {
oneImage = new Image();
oneImage.src = myImagesArray[i];
};
</script>
