|If you are still around, see if the album contains file names ending with .jpg|
If you find one or more, do a Windows search for that file name. It might show you where the original copies are stored. If you find one, the rest are likely to be in the same place.
That's why I don't really like albums - I prefer to know where my files "really" are rather than working with ghost copies.
Always pop back and let us know the outcome - thanks
