Write an action that will have something like
response.setContentType ("image/jpg");
OutputStream os = response.getOutputStream ();
while (have bytes of picture available) {
os.write (write the byte);
}
response.flush ();
repsonse.close ();
return null;
You just need to serve your JSP page as usual, linking your images to
the action above. Since for each image link browser isssues a separate
request, you should be fine with not mixing up your content types.

Same as with pictures practically no difference, except you will need to
change the content type to "application/zip", I think. We do it at my
workplace for packing the reports and it works pretty well.
