# imgur script by Bart Nagel <bart@tremby.net>
# version 4
# I release this into the public domain. Do with it what you will.

# Required: curl
#
# Optional: xsel or xclip for automatically putting the URLs on the X selection 
# for easy pasting
#
# Instructions:
# Put it somewhere in your path and maybe rename it:
# 	mv ~/Downloads/imgurbash.sh ~/bin/imgur
# Make it executable:
# 	chmod +x ~/bin/imgur
# Optional, since Alan kindly provided an API key for this script: stick your 
# API key in the top:
# 	vim ~/bin/imgur
# Upload an image:
# 	imgur images/hilarious/manfallingover.jpg
# Upload multiple images:
# 	imgur images/delicious/cake.png images/exciting/bungeejump.jpg
# The URLs will be displayed (and the delete page's URLs will be displayed on 
# stderr). If you have xsel or xclip the URLs will also be put on the X 
# selection, which you can usually paste with a middle click.
