# GIFme
# This is a really simple/stupid command line (specifically zsh) function to copy public Dropbox links to your gifs.
#
# Put this somewhere in your .zshrc and replace {{YOUR_PUBLIC_ID}} with your public Dropbox ID (find this by going to dropbox.com, finding a file in your "Public" folder, selecting it and clicking "Copy public link", and looking for the long number in the URL)
#
# This assumes your gifs (and other images you want to share) are stored in your Dropbox "Public" folder in a directory called "gifs".
# This whole thing ain't pretty, and it could be much better. But it's a start.
#
# Usage: 
# "$ gifme yup.gif" will copy a public link to "{{Dropbox Directory}}/Public/gifs/yup.gif"
