If the meta data was contained in the images, then it'd be reimported.

Manipulating the file system outside of digiKam isn't supported at the 
moment, because you can't assume that a file that was at
~/Albums/path1/file.img
is now the one that's at
~/Albums/path2/file.img

without some kind of image-data (md5, haar algo) recording and 
detection.  It's a long-standing BKO entry to provide some form of image 
checksum detection and recording - I'm hoping to try implementing a 
basic MD5 method as a proof of concept.  I do say hoping, as $dayjob is 
8 hours of coding, and when I get in I'm not too inclined to muck in c++.
