# Comments, clean up, improvements by Derek DeMoss, for Dark Horse Comics, Inc. 2015
# Added USB support, full path, support files with spaces in names, support more file formats - Tim Schwartz, 2016

# Version 0.3.3, fix: removed -r parameter from omxplayer.
# Version 0.3.2, fix: filemane 03.jpg is displayed for default delay, not 3 seconds.
# Version 0.3.1, added html support.
# Version 0.3.0, added 'pqiv -f -i blank.png&' to open blank image. This hides desktop elements.
# Version 0.2, added fbi for displaying images
# Version 0.1, moved updating playing index to the end of the loop. Otherwise playing starts from index 1 instead of 0.
