Query: One glaring omission

I thought I was going to like this book, and in fact it does cover most of the topics fairly well. It is well-organized and includes a useful CD. But it has one GLARING omission: no discussion, not even a mention, of inserting pictures. So if you have scanned images or images from a digital camera, you won't get any help from this book. This is such a common use for Powerpoint that I kept thinking I was mistaken, but it's just not there. Animation, sound files, clip art, Word Art, graphics you draw -- all are covered, but photographs and scanned images (i.e., JPEGs, GIFs, TIFFs, etc.) don't get a mention. This powerful capability of Powerpoint is my associates' (university faculty and physician-educators) stock in trade, and the real reason they use Powerpoint. Sadly, the book spends a huge amount of space on what is really trivial decoration - clip art images and Word Art. What do the author's think is important? Why do they think we use Powerpoint?
