Do you have draft as an option to the documentclass or graphicx package? –  Torbjørn T. Mar 5 '13 at 14:55

The problem is that \includegraphics seems to look from the root instead of relative to the code, so if you specify \includegraphics{folderwithfigures\systemoverview} it should work. Also pdf and svg does not seem to work, but png does.
