will work local but not on host server

[Mike G]

I worked with the CSS pop-up image viewer at:

http://www.dynamicdrive.com/style/csslibrary/item/css-popup-image-viewer/

I tweaked it to my liking, but it does not work once it is on the server. ANy suggestions?

IE: not reading (shows an 'x') thumbnail, and then shows proper picture on hover.
FireFox:no thumbnails, no pictures.

CSS:
[CODE]
<style type="text/css">
/*Credits: Dynamic Drive CSS Library */
/*URL: http://www.dynamicdrive.com/style/ */
.thumbnail{position: relative;z-index: 0;}
.thumbnail:hover{background-color: transparent;z-index: 50;}
.thumbnail span{ /*CSS for enlarged image*/
position: absolute;background-color: #405BFB;padding: 5px;left: -100px;border: 1px white;visibility: hidden;color: white;text-decoration: none;}
.thumbnail span img{ /*CSS for enlarged image*/
border-width: 0;padding: 2px;}
.thumbnail:hover span{ /*CSS for enlarged image on hover*/
visibility: visible;
top: 400px; /* position where enlarged image should offset from the top of the page */
left: 525px; /*position where enlarged image should offset horizontally */}
</style>

HTML:
<center>
<a class="thumbnail" href="#thumb"><img src="images/panel_1g-tn.JPG" width="69px" height="92px" border="0" /><span><img src="images/panel_1g.JPG" /><br /><h4>Local Electricians testing the installation.</h4></span></a>

<a class="thumbnail" href="#thumb"><img src="images/panel_2d-tn.JPG" width="92px" height="69px" border="0" /><span><img src="images/panel_2d.JPG" /><br /><h4>Great installation guys! One of six panel suites in this phase.</h4></span></a>

<a class="thumbnail" href="#thumb"><img src="images/panel_1f-tn.JPG" width="69px" height="92px" border="0" /><span><img src="images/panel_1f.JPG" /><br /><h4>Note the compact size of hardware <br>(left top).</h4></span></a></center>

Please post a link to the page on your site that contains the problematic script so we can check it out.

I imagine it's something to do with your image not being where you want it to be, or the link is wrong.

I figured it out now. The page was loading other images, so I knew the path was right. I did not realize it was important, but found out that the extensions on the files were inconsistently written upper and lower case:
-thumbnails were lower case extension .jpg
-full pictures were upper case extension .JPG
-html code asked for all upper case extensions .JPG

Result in browsers:
IE: did not mind upper case but could not find the thumbnails because the files were lower case extension.
FF: did not like upper case at all. could not even find the files that were matching with upper case extensions.

this issue may come up between different servers, as well. It's best to write *everything* lowercase unless there's a specific reason not to. (Unfortunately, some programs automatically create UPPERCASE file extensions.)
