Locked Images in PS CS?

This is new to me. Been using PS for years. I shot some pix and put the card in my reader, opened image in PS on both Mac and then on PC... and images are locked. I can resize, but can't really edit properly. Can't rotate 90 degrees without clipping part of the viewed image. Didn't do anything in the camera.

Opened same image in PSPro and I could manipulate normally. Its just PS. What gives?

Is it just the background layer locked? If so double click the layer and turn it into a normal layer.
