MY iPHONE DOESN'T RECEIVE PHOTOS?

So me and my guy friend were talking about our schedules for highschool. And he sent me a pic of his schedule, but I never got it, because ever since they updated my software, i don't know why but I can't receive photos or send any cause it will just say error. Can I fix this problem myself? I really wanted to know what classes he had, but my phone doesn't receive photos. I have the iPhone 4S, and it used. Can I fix this problem?

Try Taking It To The Apple Store, Or Call Them. You Can Go On The Website To Talk To Them Too.

Go into Settings, Messages and make sure that MMS messaging is on. Sometimes software updates turn off settings.
