Nope. Only need two at most. Each of them sets their own content type (image streamer sets it to "image/jpg", HTML producer to "text/html"). And in answer to your other question, yes, this could be reduced to just one servlet that does conditional setting of content-type and content. But you will then need a querystring (or other) key/value pair to do the conditional on. Suppose your HTML page url is /servlets/showimage/1. Suppose the "1" in the subpath is the id for the image. Then you need to have a switch in the URL to tell it whether you are getting html or image: /servlets/showimage/1?show=1
SO now your HTML page is accessed with the URL /servlets/showimage/1 and inside that page is embedded an <img src="/servlets/showimage/1?show=1" height=" + image height + " width=" + image width + " ...>. Then in your showimage servlet, you grab the "show" request parameter and, if it is present/equals 1, then set content type to image and stream the image, otherwise set content type to html and output HTML (or forward to JSP - just be sure to stick the image info somewhere in a context so you can access it in the JSP page).

HTTP/HTML, in general, doesn't work that way.
