Default [Q] CM10.2/Handcent single pic sent = slideshow of prevous

I did a search without luck

Girlfriend's Mako is on CM10.2 Stable (From a clean install, not a series) and she's using Handcent. She sent a picture to a friend of hers and it went through with a stream of additional photos in a slideshow. She sent another single photo to me as a test. I received the intended photo, along with the one that she had intended for the previous recipient along with the string of unintended photos that also went to him. I haven't had an opportunity to actually see the phone, but I thought I'd check to see if anyone's seen this issue. Not sure if it's a simple setting, a conflict between Messaging/Hangouts/Handcent or even a carrier issue. Any thoughts would be greatly appreciated.
