Find your Photos icon. When you open Photos, you'll see your pictures arranged in albums (if that's how you've arranged them) or according to when they were taken. Arranging pictures in albums makes it easier to search for them, but this isn't compulsory. Select the picture you're going to send. You can backup photos from iPhone—just tap them, and a small blue circle with a white tick inside will appear on the bottom right-hand side corner of your picture. After you select your images, tap the blue box with an arrow in the top left-hand side corner of the page. You'll get this screen. This part should be familiar to almost anyone. All you have to do now is type in the recipient's email address, bring your finger down on the send button, and voilà! Your picture (or pictures) are sent!
Uh, thanks... But that isn't even close to what I was asking. Not to mention that this thread is a few years old now.
