I just want to say that it works like out of the box! Very nice. Can't this be configurable? So you have a sub folder within images/ like wallpapers/ where all PNG images are being read from and in the ~/.paroli/ folder it is linked as bg.png? I need to restart the X server, when I do what you wrote with "pkill paroli" I got no screen back (DISPLAY is set correctly).
You can always put the picture into /media/card/ if you are running on low flash memory. The extra bonus of this is when you upgrade or flash your FR you just need to remove the default image and symlink yours from flash:
cd /usr/share/paroli/applications/paroli-launcher2/edje/default/images/ rm bg.png ln -s /media/card/what_ever_filename.png bg.png /etc/init.d/xserver-nodm restart
