Uses GM module which requires setup of GraphicsMagick or ImageMagick: https://github.com/aheckmann/gm. See below for instuctions on how to install.

##Set up

1. First install GraphicsMagick (or Image Magick. I found GraphicsMagic was easier to set up on windows)
2. For Windows go to http://www.graphicsmagick.org/download.html and click on Sourceforge and select the link next to "Looking for the latest version?"
3. On Mac brew install graphicsmagick
4. Clone this repo and cd happy-image-tester-nodejs into the folder
5. Open a terminal or cmd prompt
6. Install dependencies: npm install
7. Set Oxford API Key in environment (mac/linux or windows)
8. Start server: npm start
9. Browse to localhost:3000 to see the application in action

1. Open cmd prompt
2. Type set OXFORD_KEY=<your key>

If you want to set the environment key permanently you can use setx: setx OXFORD_KEY <your key>

1. Open terminal
2. Type export OXFORD_KEY=<your key>

If you want to set the environment key permanently you set them in your .bashrc profile on linux and on mac set them in .bash_profile.
