GoSMS mms pictures stuck in gallery

[UnsanityInc]

I can't delete pictures that were sent to me and they were put in my gs3 gallery. There is no delete option and I can't find the files on phone. Tried deleting GoSMS and they are still there. Very annoying. Any help?

I fixed it. For anyone who cares. It was a Picasa problem. I had to disable the Picasa sync them clear all data from gallery app.

What is Picasa and do I really need it syncing photos all day?
