After downloading images off of my Sony Alpha 6100 with digiKam I often see error messages like:
13:27:51 :: Connecting to camera…
13:27:51 :: Connection established.
13:28:21 :: Failed to get thumbnail for ‘DSC05709.JPG’
13:28:22 :: Failed to get thumbnail for ‘DSC05710.JPG’
13:28:22 :: Failed to get thumbnail for ‘DSC05708.JPG’
The images themselves have downloaded, so I don’t know what it means. I used Import > Memory Stick Reader to download them. I looked more closely at the the images and I think they were some images I already imported and I think I may have even deleted them off the camera with digiKam.
