actually, i might have misunderstood the problem..
if you are only trying to get an image by passing paramaters
say there is a picture on a server we want to get using a user name and pass.
You would use the doGet method for the servlet
<img src="http://localhost/servlet/ImageServlet?User=rob&Pass=bor">
then when you return the image in the servlet, use the jpeg classes included
with the jdk to encode the image, and then set the MIME type in the servlet
(so that the browser knows it is getting an image)
res.setContentType("image/jpeg"); (not sure if that is the correct MIME
type)
hopefully i understood the problem this time, and this is of help!
