I have a site which pulls lists of images from a database and displays thumbnails that, when clicked, opens popup windows the size of the image. This is all working fine apart from the browser adding a border to the top and left of the image. The border is about 15 px.

Using javascript to open a window, you must either supply the html for the page that opens in the second window, or else the body will have a default margin
If you are pulling the size of the thumbnail image from a record set, just add something like 30 or 50 pixels to the dimensions to allow for it, otherwise you would have to use document.write()

the margin can be set to zero using

     body { margin:0px; }

in a style sheet, or

   <body marginwidth="0" marginheight="0"
         leftmargin="0" topmargin="0">

in the html

Is there a way to make the submit buttons different colors?

You can use a stylesheet to control the button:

  <input type="submit" style="background-color: #F00">

Or you can use an image for the button:

  <input type="image" src="/images/button.gif">

Can someone tell me in a SIMPLE sentence or two, just what does Cold Fusion do?

Cold Fusion is for server-side processing; this *includes* accessing a database, but that is *not* all it does. Cold Fusion can do all sorts of really neat stuff besides database, and it is much easier to learn than other languages.
A great place to start on learning ColdFusion: http://hotwired.lycos.com/webmonkey/programming/coldfusion/
I particularly recommend http://hotwired.lycos.com/webmonkey/programming/coldfusion/tutorials/tutorial2.html

Just started looking at z-index in the hope that it might make the HTML table variation <tbody> function actually work.
Two points I haven't got my mind around at the moment :

It seems that you have to have overlapping elements for it to work?
Testing in IE 5.5 I am getting variable results in the use of element definitions [ but that could just be me, lol ] in different tags.

After a little fooling around I came up with this table below. It features a stationary table head, and scrolling body. Just might be what you've got in mind. Take a look.

Hold your position!

The HTML for the above table:


<table  	width	= "400" 
	cellpadding	= "4" 
	cellspacing	= "3" 
	bgcolor		= "#333333"
	border		= "0">
	<th bgcolor="#aaaaee">
		Hold your position!
	</th>
	<tbody  bgcolor="#ffffdd">
		<td  style	= "padding:0;" 
			align	= "center" 
			valign	= "middle"
			height	= "25">
	<span style="height:25px; width:100%; line-height:25px;
overflow:auto;">
		text and text and text and text<br />
