samsung epic 4g flashed to boost not sending pics

[blessedsilence]

I flashed my epic to boost like 6 months ago. Due to an accidental deletion, my phone had to be reset. Now I am unable to send pics. I can receive them, though. I can get on the net, make and receive calls, everything except send pics. I downloaded an app that allows the pics to be sent but its just kind of a pain. Anyway, I was wondering how can I solve this issue?
