[Digikam-users] Digikam not recognising already downloaded photos - solved for me at least

Sun Aug 19 08:50:36 BST 2012

Well after waiting to get my main PC back from repair I have had another 
look at this.

I had my camera added manually but of course when it gets plugged in it 
is auto detected as well and I believe having two instances of the same 
camera is causing the problem because I removed the manually added copy 
and lo and behold it now remembers which photos are already downloaded.

So for me the problem seems solved for me at least. Dont know if this 
helps others who have the problem.
