Sending high quality photos from your iPhone via Mail and Messages
Messages is an easier option because you can send more photos at once, about 20 versus 6 through Mail
When emailing photos from your iPhone please follow these steps:

Open your Photos App from your home screen
Click on the Select button and then select the photos that you want to send one by one. (Click on an image again to de-select it).
To avoid warnings, I would recommend breaking up your emails into 5 photos per message.

When you are done selecting images, click on the send button and select Mail


Select Actual Size, that's it, you're done!
Unless you got a warning about size :(
If it says try, go for it. It might bounce back in a few minutes, if it does you'll need to send your photo in smaller batches. Stay under 15mb-20mb
When messaging photos from your iPhone please follow these steps:

Click on the Settings Button on your home screen
then Messages

and makes sure that Low Quality Image Mode is not selected
(not green as shown)

Open your Photos App from your home screen
Click on the Select button and then select the photos that you want to send one by one. (Click on an image again to de-select it).
You can message a lot more through messages than email, I got away with 20, if you choose too many, the Message option will not be available, at that point you will need to deselect some.

then just fill out your Message and hit send
When you are done selecting images, click on the send button and select Messages
