What does the URL in your browser look like when you are access the JSP 
pages?  The browser constructs the full path to the image from the URL 
used to request the page (JSP or HTML -- the browser doesn't know the 
difference).

Nope.  They are "rooted" right where they are although internal 
forwarding can make the request URL different from the actual location 
of the JSP.  In the past, I've done stuff like <img 
src="${pageContext.request.contextPath}/WebContent/image.jpg"> to get 
around these issues with an absolute path to the image.  My example 
assumes a servlet spec 2.4 webapp and container.
