Added pictures

Added a bunch of pictures to the e-book today to see what they would look like - most of them look good, but I do need to enlarge some of them.  Plan to do that tomorrow, as well as delete the space that I ended up creating at the top of the chapter headings.  Also took out the few bulleted lists I'd put in, because they didn't look good on there.  Also figured out how to turn off full justification, which I hate - it completely screws up the spacing in the sentences.
