images not displayed in firefox 3.0.1

[Stefan]

Hi!

I am using the following code to dynamically create a table displaying users stored in a database.

I am creating hyperlinks with small icons for actions you can perform on users.

This works fine in IE, but in Firefox (3.0.1) only the 'alt' text gets showed.

If I directly enter the url of an icon, firefox shows it.
Can someone figure out what might be the problem ?
