Gika and shaybe, indeed there was a error (an extra space) on the support extensions listed that avoided jpg images to be shown.
A fix will be available soon.
Please try again as soon as we update the pause file to see if the bug is fixed.
bartmarley, your problem have no relation with the above mentioned bug. Folders, pdfs and so on keep working as always have been on any of my tests.
Please try to reset your pause settings, check your pause media folder names and create another thread with a log and screenshots of your folders if you want my help trying to figure out what is going on on your setup.
PS: Djvj, you are certain that I didn't change anything on pause on the last versions. However, the above extra space bug was introduced by someone else that messed with my code to change the supported image extensions definition to use := intead of =. I am not pointing fingers to anyone, but it is clear to me who did that
