Hello,I am using a slide show script on one of my sites. I like most of it except that it preloads every image before it lets you start scrolling the images. I get alot of complaints from Dial Up users because of this. Ill be using around 15 images a week that are around 12k a piece and at 300x225.
I like the fading effect,but id sacrifice that in order to have a faster load time.
Is there any way to modify this script so the preloading is only for the first 2 or 3 images or is there another script out there that is better for non broadband. Basically Id like to remove the fade effect if need be and the preload if i have no other options...thanks for any help.
script example: http://www.codelifter.com/main/javascript/slideshow4.html

<!--
Add onload='showHot=true;' to the body tag. This is
needed to prevent false object calls while the page
is loading. Optional: If you are using this in a
popup, as in this demo, adding self.focus() to the
onload event in the body tag will bring the popup
to the front each time it is loaded [recommended].
//-->

<!--
The following table holds the images, captions, and controls.
Place the table in your page where you want the slideshow
to appear. Follow the instructions for each table cell.
//-->
<div align="center">
<center>
<table border=0 cellpadding=10 cellspacing=0>
<tr>
<!--
The next table cell holds the images.
Set cell and image width and height the same.
The img src must have name=PictureBox in its
tag. Often, the first image in the Picture
array in the script is used here; but you
may also use a different, introductory image
as we have here, since this image is shown
only on start-up.
//-->
<td width=350 height=280 colspan="3">
<img src=Nebula00.gif name=PictureBox width=350 height=280>
</td>
</tr>
<tr>
<!--
The next table cell holds the captions.
This table cell must have id=CaptionBox and
class=Caption in its tag. The default caption
shows whilst loading in all browsers; NS4
will show only the default caption, throughout.
//-->
<td id=CaptionBox class=Caption align=center colspan="3">
This is the default caption.
</td>
</tr>
<!--
The following three cells contain the controls.
Each of the control a href's must contain class=
Controls, to attach the styles (see top of script).
To dress this up a bit, you can of course substitute
<img src> images for the text in the links.
//-->

<td align="center">
<a class=Controls href="#" onClick="javascript:control('B');">< <</a>
</td>
<td align="center">
