My profile looks like:The image should be cropped so that it doesn't overlap with the rest of the profile. It seems to work with other image formats.

I like them because you get almost instantaneous feedback on legitimate problems.

The chapter is longer, but it's fairly comprehensive because of it. My thinking is that if you buy the book because you want to migrate an existing version 1.1 web service to the new and improved version 2.0, then you'll be covered, for you'll know where the differences between each version are.
