What does this have to do with java? You can just wrap your `img` tag with an `a`: `` — beerbajay, May 22 '12 at 08:10

In your case, you should set the content-type to image/jpeg

When you wrap an image with a href, on clicking that link you can view that image in the web browser itself. To download it you will have to right click and give save link as and then choose the directory where you want to store the file.
But if you strictly want to download on the click of the link itself, the you can use a form.
For example :
give the link location to a servlet called containing :

In "your servlet"'s doGet() method, do as Aaron Digulla has pointed out https://stackoverflow.com/a/1134128/34088 use :

byte[] data = getBinaryFromSomeWhere(request.getParameter("xyz"));
response.setContentType("image/jpeg");
request.setHeader("Content-length", Integer.toString(data.length));
out.write( data, start, end );
out.flush();

The file will be saved in your system.
