Yes, there is:
Select the changed image(s) and select "Recalculate Checksum" from the 
Maintenance menu.

When you change images (even without visible changes) you should always 
recalculate the image checksum so that KPhotoAlbum can recognize renamed files 
without losing the tag data etc. Once KPhotoAlbum realizes that the checksum 
was changed, it also recreates the thumbnail...

Cheers,
