Hello,
I'm using a Microsoft LifeCam with SimpleCV on the ipython interpreter(or shell) on a Raspberry Pi 3 model B(with Raspbian, tell me if you need the exact OS version as it's quite complicated). 

I'm following the directions of a book: Raspberry Pi Cookbook by Simon Monk.
I get this error:
SimpleCV:1> c = Camera()

SimpleCV:2> i = c.getImage()

SimpleCV:3> i
SimpleCV:3: <SimpleCV.Image Object size:(640, 480), filename: (None), at memory location: (0x6efdfc88)>

SimpleCV:4> 

SimpleCV:4> i.show()

I(Michael J or "MJ" as I'm commonly called) have searched for the directory myself, and I can tell you, it's not there.

Tell me if you need more information, as I will be glad to assist.

I'm sorry for any inconvenience caused by me using ipython if it's unfamiliar.
