Sitepoint Book: Photoshop CS6 Unlocked

Good morning.

I am a bit stuck on Chapter 4 of this Sitepoint book on the section on Photographic Backgrounds, page 140.

I cannot locate the original coffee beans image that I am supposed to work from.

There is the finished tiled psd file in the Photoshop download that comes with the book but I cannot find anything else.

Can anyone point me in the right direction?
