iOS device users have been able to share photos and videos from the Camera Roll since the very first iPhone was released in 2007, however this feature has traditionally required the user to start in the Photos app to select the items they want to share and then create an entirely new e-mail message from there with the photos attached. Unfortunately, this method doesn’t work particularly well if you’ve already started writing an e-mail message and then later decide that you want to add one or more photos to it.
While the iOS clipboard would allow you to copy and paste photos, switching back and forth between the Photos and Mail apps can still be a bit cumbersome.
Fortunately, iOS 6 adds the ability to attach photos and videos directly into an e-mail without having to actually leave the Mail app at all.
Simply tap and hold on an empty spot in the message to bring up the context menu and then tap on the right arrow to reveal an “Insert Photo or Video” option. This will bring up the in-app photo browser from which you can choose a photo to insert directly into your e-mail right at the current cursor position.
