摘要：
A technology for automatically saving an original copy of an image file in a location hidden from a user is disclosed. The technology accesses metadata associated with an image file and determines whether an original copy of the image file exists. Provided an original copy of the image file exists, an edited version of the image file along with an identifier is saved. If an original copy of the image file does not exist, an original copy of the image file is created, the original copy of the image file is stored, and an edited version of the image file along with an identifier is saved.
