Why can't I send/recieve picture messages?

[AC Question]

I have an LG Access LTE from straight talk. Its not a popular phone but this is the only problem it's given me! When I send the message, it shows like a broken picture icon and acts like it's sending and sending but never does. PLEASE HELP ME!

Welcome to the forums. Is this with the text app?
