Comment 4 for bug 821915

Vincent,

If we want this sort of drag and drop to work, Shotwell will need to keep an on-disk copy of each photo including all edits the user has made. Today, Shotwell only keeps the originals on disk, and applies the user's edits on the fly each time the user opens a photo. As a result, fixing this will be a large change to Shotwell. (See http://redmine.yorba.org/issues/1798.) It certainly won't happen for the upcoming 0.11 release. Perhaps we'll be able to implement this for 0.12 or 0.13 depending on other priorities.
