Duplicates patch new version - Check box in importing

- Date: Wed, 28 Sep 2005 06:04:10 +0200
Hi guys!
Some days ago I have modified the Duplicates patch in order to be more
user friendly. When you are importing photos you have a new checkbox in
the import dialog so you can enable or disable it in order to import or
not to import the duplicates photos. You can see it in this screenshot:
http://acs.barrapunto.org/~acs/Duplicates-Checkbox.jpg
Here goes the updated patch with the new needed file
DuplicatesFinder.cs.
I hope we are closer to commit it upstream.
Cheers
-- Alvaro
