SD Card loading is too large for 168 chip

[Andon-A]

The sketch that loads images from the SD card is a little bit too large. It uses 144% of program storage space and 117% of dynamic memory when attempting to load for a 168 chip like what is found on the regular badge.

It would be greatly beneficial to add this to the examples of what the 168 can do. However, it is beyond my capabilities. I'm not a terribly good coder, and the actual image loading is well beyond me (Thankfully there was something I could bastardize to make it work).
