[Digikam-users] How to update photo collections?

[Kim]

I'm having a "silly" but frustrating problem.  When I set up digikam I 
set my collection folders under Settings - Configure digikam.
I used the Collections menu there to set up the album folders.
I have some folders for photos I take, and others for genealogy records.
When I import images using my SD card DK adds the new folder to the 
collection fine.  BUT when I download record images and manually make a 
folder in my dropbox folder and put the new images in there, DK is not 
updating the folder list in dropbox when I open DK.

I can't figure out how to get it to find the new folders or images.
Since I organize my document folders with many subfolders by 
topic/family it would be very hard to figure out what folders DK has not 
imported since I set it up.

Going to Browse - Refresh does not show the newer folders.

I thought of using Import - Folders and having it import my dropbox 
folder again, BUT it looks like it's copying all the folders and images 
into another place??  Or is it just bringing in links to the newer files 
and photos?

Any other photo album/editor I've used before Picassa or Photo Shop 
Elements have always recognized when I opened it to check the marked 
folders for new images.  I'm not understanding  how to have DK do this.

Hopefully there is an easy way to do this, I just can't find it.
Thanks,
Kim
