On version 5 when, as a user, I try to preview an image file (jpeg), I get the error message 'preview not available' - any suggestions on why that is? On the demo, I had no problem.

Take a look at http://wiki.openkm.com/index.php/Applic ... nt_preview. If you miss anything, please tell us to improve the documentation.
