instapusher.py

#!/usr/bin/env python
# -*- coding: utf-8 -*-

# Instapusher. Push images from a directory automatically to Instagram.

# Schedule script with cron eg:

# 0 18 * * * /path/to/instapusher --login <your_username> \
#            --password <your_password> --random-delay 30 <dir>

# Give working directory in form /path/to/dir
# The directory structure contains two subdirs and they should contain presized
# 1080x1080px jpg-files:
# directory/todo  <- contains jpg images to send randomly by this script
# directory/sent  <- images that have been sent are moved here

# Example file listing
# /Users/you/instapush-dir/sent/possible bugfix #coding.jpg
# /Users/you/instapush-dir/sent/this one too #stackoverflow.jpg
# /Users/you/instapush-dir/todo/this pic is going to change the world.jpg
