Where are the images?

[mcourteaux]

After struggling for an hour trying to compile this, I finally did. I managed to get the shaders working, but there are missing images.

[ error ] ofImage: loadImage(): couldn't load image from "images/ref-img.png"
[ error ] ofImage: loadImage(): couldn't load image from "images/noise-bg-color-darker.png"
[ error ] ofImage: loadImage(): couldn't load image from "images/noise-bg-color-darker.png"
[ error ] ofImage: loadImage(): couldn't load image from "images/ref-img.png"

I can't seem to find them anywhere in the repository. And if for some reason you don't want to add them to the repository, what are they supposed to look like and what sizes?
