Two things I like are:

• The Command + Shift + 4 shortcut for taking screenshots (OS X).
• The world wide web

So why not combine the two? This mini-project turns the screen capture utility on OS X into a lean, mean image uploading machine.

Install

1. sudo mv /usr/sbin/screencapture /usr/sbin/screencapture-bin
2. sudo sh -c 'curl https://raw.github.com/borismus/screencapture-www/master/screencapture > /usr/sbin/screencapture'
3. sudo chmod +x /usr/sbin/screencapture

Uninstall

1. sudo mv /usr/sbin/screencapture-bin /usr/sbin/screencapture
