I know this idea has been mentioned before, but I think it's up for discussion on whether it'd be a good add-on for FAP. Meaning.... someone should really code it! hah.
I think it's useful to replace a photo that you've corrected (brightness/saturation, flaws, etc) that already has comments on it.. rather than uploading a new one and taking up even more space if you want to leave the comments+photo.. or losing your comments altogether.
What do others thing?
