Ability to store Original File
I am starting to receive photos in non-Jpeg formats - notably .heic, but I suspect more new types may be on the way. I convert these externally to JPEG and import them, but it would be useful to be able to store the original with the other files. The files names should not clash, as they are non Jpegs. The database could have an original_file field for a photo, to hold the filename, and possibly an original_desc for descriptive text.
In photo edit there could be an 'upload original' button, and in photo display a 'download original' if there was one.
This would also allow a simplistic implementation of being able to store movies (#9) by extracting a jpeg as the sample image for the movie using an external tool, importing that as normal, and then upload the associated movie.
