My VSD designed website contains many images. I have inserted highslide CSS script in both the header of pages with images and in the Body HTML of the particular image. The initial image on the web page is a thumbnail. When you mouse over the image, highslide causes a small magnifying glass to appear. When you click on it, the image enlarges on the page, that is, the full-sized jpg image appears along with a caption. When you click again, it returns to a thumbnail.
I know the CSS works; I've seen it work in VSD Preview. But in trying to get my website up, I had to change folder names because image files were not being recognized. Somehow in this process I have messed up the CSS. The complete highslide file is there on the website -- I see it in cpanel -- but the script is not being recognized. What happens now is when you point to a thumb, a small hand appears. Click on it and the full jpg image opens on a separate white page without a caption. I know from past experience that this means the site cannot find the CSS. It also can no longer find the CSS in VSD preview.
Below is the formerly-working CSS script. I suspect any Good Samaritan may also have to view my website. Unfortunately it is password protected because I wanted to work out bugs such as this one before the site went public. If you don't have any generic solutions, tell me how to get you a User Name and Password without broadcasting it. I'm desperate for any help you can give me.

HEAD (same for every page with images)
<http equiv="Content Type" content="text/html; charset=utf 8" />
<script type="text/javascript" src="highslide/highslide.js">
</script><link rel="stylesheet" type="text/css"
href="highslide/highslide.css" />
<script type="text/javascript">
hs.graphicsDir = 'highslide/graphics/';
hs.showCredits = false;
hs.outlineType = 'outer-glow';
hs.wrapperClassName = 'outer-glow';
</script>

BODY (generic -- differs with each image)
<div>
<a href="pix/FullImage.jpg"
class="highslide" onclick="return hs.expand(this, { captionText: 'place the caption here'} )">
<img src="pix/Thumb.gif"
title="Click to enlarge" height="100" width="100" />
</a></div>

A link to your page would be useful...

You may need to contact the creators of highslide.

Inger, I have sent the information to your email at cybeer. Cary, I probably will in the end. Thanks for the replies.

Inger, disregard my email. I reloaded all my highslide files and the website now works properly.
