Transferring the EXIF date from one image to another.

[svennbg]

Often additional image files are stored in a folder where the EXIF date does not match the rest of the photos, so the sort order is not correct.

Example:
Photos from a visit to a restaurant or museum:
I took photos of the visit (with correct EXIF date).
And I complete the collection with a scan of the receipt or ticket.
The scan has no EXIF date or the date of the scan time.
I want the file with the receipt or ticket to get the EXIF date from the other photos.

So far I had to enter the correct date manually (using cmd_changeTime).

Here a tool would be great that works like this:
1. select both files.
2. a dialog appears that shows both image files and the existing EXIF dates.
3. transfer EXIF data from file 1 to file 2 (or vice versa).

I think this would be tricky to implement, since I can't even figure it out using the exiv2 command-line tools.
