Like the "javascripty" term.
In actuality I'd probably not use the iframe solution, but the OP was wanting the photos to show in a "box" which made me think of an iframe. Recently I've been using HTML5/CSS3/jQuery for photo displays/galleries/sliders -- much more elegant. OP can do some Googling for that -- lots of solutions out there.
The other thing I did with my code above was get rid of the <center> tag -- deprecated since XHTML 1.0 strict (?), and completely unsupported in HTML5 -- futureproofing...
Since my previous code was "unique"
here's more or less the same thing that validates for HTML5:
<!DOCTYPE html>
<html>
<head>
<title>My Contacts</title>
<meta charset="UTF-8">
<style>
body{
margin-top:200px;
font-family:Georgia, "Times New Roman", Times, serif;
}
#picdisplay{
text-align:center;
}
</style>
</head>
<body>
<div id="picdisplay">
<iframe id="display" name="display" width="300" height="300" seamless src="Photo96.png"></iframe>
<a href="Photo97.png" target="display">Get Photo97</a>
<a href="Photo98.png" target="display">Get Photo98</a>
</div>
</body>
</html>
