I don't understand Your problem.
Please be more precise.
Why not use response.sendRedirect("http://www.somewhere.com/image.gif");
It works for me.
I am using a pageid parameter to identify the page from where was called
the servlet.
Like this :
<img src="http://somewhere/servlets/BasicSnooperServlet?pageid=2">
Hope it helps.
Best wishes,
Andras
