First, the content type for a GIF image is "image/gif", not "text/gif".
You are correct that you can not mix text and image output in the same
page. What you need to do is include a normal image link, like this:
<img src="xxxxx">
in the text output of your servlet (just as if you were authoring a
stand-alone HTML page).
Now, what is "xxxxx"? Well, if the images you are talking about are
available at a particular URL on your web server, just use that URL and
the browser will download it in the usual way.
It is also possible to have a servlet dynamically create an image, by
using a URL that points back at your servlet. An example is where you
might be constructing a graph image on the fly, using some graphics
library. You will need to do something in the URL to tell your servlet to
return the image instead of a text page.
The browser will request this URL on a separate request from the one that
is causing your page to be created, so you never have to mix text and
binary data on the same request.
