Checksum option #34

[2014/06/11] Seems like a reasonable idea. Since it will slow down image processing this would be implemented as an optional mode. It could also potentially be used to compare different files (eg. renamed, stripped metadata) to identify likely equivalency. |

It would be very useful to have an option to generate a checksum of the images in JPEG files. Not the thumbnails, just the main image both to individual output and batch processing.
Whilst on its own a checksum is meaningless, it would be extremely useful for comparing multiple versions of the same image since matching checksums would guarantee any differences in the file (whether due intentional or unintentional changes) were in the metadata only.
