#
# This script posts pictures from a given directory
# to a given DIASPORA-Account. It posts one picture per round.
# Subfolders are not supported.
#
# Requires:
#		- python3
#		- diaspy   (do a manual install via https://github.com/marekjm/diaspy)
#
# Usage:
#		# script will fail if it is not called from picturefolder!!
#		$:>  cd /path/to/picturefolder							
# 		$:>  /path/to/pic2diaspora.py
#
# This script will create the file "0archive_posted.txt"
# in the given picture directory (check for write permission). 
# In this textfile, filenames of pictures already posted are stored.
#
# The script looks up all pictures in the given directory
# and compares their filenames with "0archive_posted.txt"
# This script won't upload any pictures included in "0archive_posted.txt"
# The script will take the first "new" pictures it finds, post it to Diaspora and exit. 
# If there is a .txt-file with the same basename as the picture-file (e.g. "picture1.jpg" and "picture1.txt")
# The txt-file's content will be posted along with the picture.
# 
# So, one picture is posted per round. Thus, the script is ment to be run via cronjob.
#  # Cron.Example:
#  # post a picture every 6 hours 
#  0 */6 * * * 	cd /path/to/picturefolder; /path/to/pic2diaspora.py
