upload images to your imgur account from the command line

my_imgurup.sh

#!/bin/bash

# To use, create ~/.myimgurup, and put in your client ID and secret
# E.g.:
# CLIENT_ID=80238f8092
# CLIENT_SECRET=239a482b034c820
#
# Next run `base /path/to/my_imgurup.sh auth` to get your PIN and access token
# Finally, `base /path/to/my_imgurup.sh up /path/to/image.png` to upload an image
