This post will show you the two ways that you can email photos from an iphone and an ipad
the first way:
direct from mail:
open mail, compose a new mail to someone as usual
touch and hold on the body of the email, as if you were going to paste some text
you will now see that there is a new entry for ‘insert a photo or video’
click that and you can select the images you want to mail
hit send
the second way:
open the photos app
click on the photo you want to email, or press the edit button and select multiple photos
click the share icon
click email.
send your mail :)
