Wicket 1.2 -> 1.3 upgrade question

Wicket 1.3 is configured as a filter rather than as a servlet.  The
Quickstart shows a filter whose URL-PATTERN is "/*".
 
The project that I wish to upgrade contains two Wicket 1.2 application
servlets (two different home-pages accessed via different URLs), and one
plain-vanilla non-Wicket servlet.  They are deployed together because
they share the same code-base.
 
This is my Wicket 1.2 project's web.xml file.  How do I do this sort of
thing in Wicket 1.3?

Wouldn't surrounding your <img> tag with <wicket:link> help?
