Images disappear in IE

Why have my thumbnail images disappeared on a particular page in IE6 & 7? Currently I have a popup window that opens up playlist.html on the correct mp3 player. On Firefox/Safari the images are there. The code validates.

Here's the website:

Here's the offending page:
http://www.oneact.org/playlist.html

<a name="CaesarAndCleo"><img src="playlist_files/CaesarAndCleo.jpg" alt="Caesar and Cleo"></a>
<div id="CaesarAndCleo">........
IE DOM might be getting confused by the attribute values of these set of elements. Have a try by changing any one of them.

That was indeed the problem. I added an underscore to the "name" element and all was well.. Thank you
