You have to do it from the camera roll.
You can select up to 5 pictures.
Then press "share".
That's not true. You can paste any picture. I just did it. Also, the trick to get more than one is to put some lines spaces in first, otherwise you have no place to paste the next pic. I would imagine there's also no limit (unlike what the poster said above about 5) ot the pics you can send other than the mail size limit.
haha true, I didn't think of it before
