 To add new servlets, program the servlet code in the application source packages. Then add the servlet-mapping definitions as usual to the web.xml file.
+
+== Embedding images in webpages ==
+The local gnowsis server runs at 127.0.0.1:9993, for a web-browser this looks like any webserver. So the webbrowser will allow you to embed images in your web-applications if they have URLs that point to web images, not to file images on your harddisk.
+{{{
+<img src="picture.jpg" />
+<img src="/gnowsis-server/picture.jpg" />
+<img src="http://example.com/picture.jpg" />
+
+this is not allowed due to security restrictions in the web browser:
+<img src="file:/C:/picture.jpg" />
+
+}}}
+
+As a workaround we provided a servlet that loads local images and returns them, it works like this:
+{{{
+<img src="/gnowsis-server/showimage?uri=file:/C:/picture.jpg" />
+<!-- long version -->
+<img src="http://127.0.0.1:9993/gnowsis-server/showimage?url=file:/C:/1/pic.jpg" />
+}}}
