why cant i send a email text ?
Welcome to iMore! Are you talking about the messages app or email in the Mail app?
If the messages app, there's been some problems with the app freezing up and other issues in iOS 8. Try a force quit of the app. Double Tap the home button and swipe out the messages app.
Also, it could be the photo resolution size is large, making it hard to send. In this case, long press the photo and tap "More". Then delete it. Try again by sending the photo by itself with no text.
