Photoshop :: Create Action To Put Watermark And Gold Frame On Photos

I'm trying to create an action to put a watermark and gold frame on photos (Photoshop CS6). I will need to add it to many photos at a time (100+) so plan to add it to a folder using automate, batch. I've created the action and when I use it on another image to test it the frame doesn't fit, it's really blown up and warped. The two images are the same size, neither have been cropped at all, I used the same camera, same lens, everything is the same, so why doesn't it fit?

I'm guessing it's something to do with the size of the gold frame image as the actual watermark is fine, but I'm a bit confused, it's as if the two images are different sizes or one has been cropped, but this isn't the case.

P.S The photos are just to test the action, I'm not actually giving a gold frame to the wedding photos!
