You forgot tracker.waitForID( 0 );
You can not use the simple "collage.gif" form because you don't know what the JVM's current directory is - use a complete file address.
If you didn't see the Width= message, I bet you threw an IOException and didn't catch it.
Declaring an errorPage is your friend when debugging JSP.
