Once you have your table structure you need to look at adding your images into each cell (between the <td></td> code). The code needed would be...

<img src="myfirstimagethumb.jpg" border=0>

but to get this to link to the javascript code for each larger popup image is like this...

<a href="javascript : popupmyimage_1 ();"><img src="myfirstimagethumb.jpg"></a> (there should be no spaces, but the site put a :p in instead of what is shown lol)

This would be entered into very cell for everyimage. Getting a bit cluttered in there...

So if you are able to use PHP or ASP on your host let me know and I can show you the code to get you connected to an access database test it and then dynamicly link each image using one javascript link and one line of code for the table.

My gallery uses a language called Coldfusion and is done with this technique, of a database and single bits of code.

Hope it helpls, and you might want to chekc out this free site on Web Tutorials.
