Dear users of this site. A major systems upgrade was necessary for security reasons. We have upgraded from Drupal 5.2 to 5.3. At first all went well but then actions of the sysadmin from hell (me) triggered a chain of events which ended almost disastrously. However, the site has been restored (almost) to full functionality. The images work again, yet there are issues with thumbnail images (I think youcan all see the error messages). Update to the update: As far as I can see all images are displayed again. We are now using imagemagick as toolkit.
