The best way, IMO, is to not use GWT-RPC, but rather implement an
HttpServlet, that retrieves the data from the database and returns it with
the appropriate Content-Type in response to a GET http request. Then, you
simply place an image in your GWT code, with its source being the path to
the servlet (defined in your web.xml), passing along any parameters required
- such as the ID of the image in the database.
