 # Getting Started
 
 1.  Download the demo example ([zip](https://github.com/s-ben/Fractal-Mosaics/raw/gh-pages/code/fractal_mosaics.zip), [tgz](https://github.com/s-ben/Fractal-Mosaics/raw/gh-pages/code/fractal_mosaics.tgz)).  
-2.	Download the [example image set](https://docs.google.com/file/d/0B_2ApIVBvXm1RlFjTmVwUXRIcms/edit?usp=sharing) (706 MB database of greyscale images of San Francisco).
+2.	Download the [example image set](https://docs.google.com/file/d/0B_2ApIVBvXm1RlFjTmVwUXRIcms/edit?usp=sharing) (9.1 GB database of greyscale images of graffiti).
 3.	Unpack the zip file containing the example image set and copy its contents into the /library_images folder in the demo example.
 4.	Navigate to the /m-files directory 
 5.	Run ‘fractal_mosaic.m’ 
 
 Your mosaic is now rendering.

 The demo example creates a black and white mosaic.  This is because color takes ~3X as long.  To create a color mosaic, download the [color image set](https://docs.google.com/file/d/0B_2ApIVBv Xm1ckhjX3RibVVPdkk/edit?usp=sharing) (COMING SOON), and set Fractal Mosaics to color mode (see the [Variables](https://github.com/s-ben/Fractal-Mosaics/wiki/Variables) page for info on this).
