LG G3 :: How To Get Phone To Send Picture Messages

I'm extremely irritated at this point, because it's been one thing after the other with my phone. It has more problems than my BMW. The phone's gotten better, but this is still a problem.

I use Verizon Message+ for texting, and my phone says "failed" every time I try to send a picture message. It's really annoying, and from what I can tell, it's a fairly common problem with LG phones on Verizon.

I've tried resetting the app and changing settings, but nothing seems to work.
