I'm on 7.0.4 IOS and have the same issue. I have to reboot device then it works fine for a while. It must be a bug and hope apple releases a fix.

I just sent myself a photo by selecting a photo then message. Everything went fine. Try a reset, press and hold the home and power buttons 10-15 seconds till the Apple logo appears. Release both buttons. Wait 15-20 seconds till your iPad starts on it's own. Message yourself a photo to see if it worked.
