Change photo path

This would be extremely helpful as scenes are being set up and processed on separate machines and we have been doing a lot of image prep/masking tests that yield great results but its always difficult because we only have one option.  Which is to overwrite the images in the directory.  It would also be nice to be able to switch from file types, like tiff>jpg files for example without losing masking data.

Thanks!
