Hello Brenda, I would consider water misting the back side of the frame- lie flat on firm (concrete) floor with board/plywood on top, then weighting it down to attempt reshape it.
Hi Brenda! I've listed a few great places to gain information and help on this project. I wish you the best!

Brenda, Try using a picture hanger in the corner where it's warped... It's a half Moon shape, then screw into the back of the frame. Push the frame into the half moon so the screw catches, and it should catch. This should work. Aloha!
