# Helper script for Simple Folder Gallery plugin. This accepts one or more directory names and processes the
# images and thumbnails for proper sizing and also generates the title.txt, date.txt & hd.txt files that the
# plugin expects. The user can also create a key.txt file containing the filename of the "album cover" otherwise
# the plugin will simply use the first file found.

# CHANGE obase TO THE DIRECTORY WHERE YOUR TOP LEVEL photos DIRECTORY IS. THAT MIGHT BE SOMETHING LIKE:
# /home1/c430947/public_html/wp/photos OR /home3/c212725/public_html/photos DEPENDING ON YOUR SERVER SETTINGS
