The images we have in the TAG right were generated in dia and aren't very nice at all. We should try to make something more flashy.
We will handle this by outsourcing most of the work. Still need to spend some time on management though.
doc/external/images/sysarch.png lacks the HTML5 client completely.
Found a tool name draw which is very nice and is a open source (GPLv3) HTML5 diagram tool . Where content produced with the tool and all available cliparts are free to use for any purpose. This tool was used to fix the sysarch image in bug #5817.
