How can I text / MMS multiple photos from the iPhone?

You may have tried to send more than one picture to your friends via the Messages app on iOS. Currently there's no way to add more photos when sending an MMS, that is unless you open the Photos app and do it from there.

The process is simple, just open Photos and go to the Album or Camera Roll to choose the pictures you want to text. Tap the arrow button in the upper right hand corner. Tap the photos you wish to send via MMS, and a red check mark will appear over the photos selected.

Now touch the Share button in the lower left hand corner of the display. You will have the choice of Email, Message, or Print. Tap Message to open a new MMS in the Messages app with your selected photos. Now you can add recipients and text as normal, but with more photos.
