At an Apple seminar in Jenison today I learned that in iOS 9 the Mail app now has a camera icon above the keyboard when you type in the body of the message.
Once you have inserted your picture, tap it to bring up a toolbar with the new "Markup" choice.
Mark up your picture with a set of drawing, text, and signature tools.
This is a great addition that allows us to communicate more clearly and then saves a bundle of time without having to mark up pictures in additional apps.
