Query: All is on the net

We were really disappointed when we discovered this book. I was looking for JFIF file format explanations, and they only explain in detail common formats like BMP (et encore !!!) that you can find anywhere on the net. So really just a review of internet, useful for the one that has no printer. Really if i could get my money back i would do it.
