Hi all!
I found that is difficult to search a simple javascript code about scrolling image slide. You can find them on Internet but they often are long and complex or hidden from us to prevent edit.
I just found a simple way to resolve this. I hope it will help your editting easier to make it yours!
We need 2 div tag to make a slide. ChildDiv to store image array and ParentDiv to contain Child Div.

Note:
Image Array's Structure: [<Image's Link>, <Image's Width>, <URL to Go>]
Functions:
DoSlide(), Make Slide to run.
setmouse(param), set Slide play and pause when pointer over or out on images;
Dr_ImgArr(); Print image array to HTML;
getE(), getElementById();
DivWidth: Width of ParentDiv;
MoreImage: Num Of Image on a begin of Image Array, insert into the last of ChildDiv to continue the Slide;
....
If you have anymore comment, please reply here so that I can make it more perfect,
thank for all.

Style

CODE

<style>
#ParentDiv
{
    margin: auto;
    width: 600px;
    overflow: hidden;
}

#ChildDiv
{
    width: 6000px;
    position:relative;
    cursor:pointer;
}
#ParentDiv img
{
float: left;
padding: 3px;
margin: 0px;
}
</style>

Javascript

CODE

<script>
//Array Of Image, [URL, width of Image, LinkTo]
var t;
var StepTime=10;
var StepPixel=1;
var ImgPadding=3;
var ParentDivLen=600;

Thanks for sharing this. One suggestion is to place more comments in your code for other users to know what is going on and where.

Er... couldn't the HTML tag <marquee> do this?

It is deprecated, but seems better than using a ridiculous amount of javascript and divs to achieve the same effect.
