Downloading photos from an SD card
I appear to have successfully downloaded photos from an SD into Lightroom; they appear where I am making a photo book. I have loaded some of these photos in the photo book. But they have a red exclamation mark on the photos, with a note that they will not print.
Have I downloaded them incorrectly?
Any suggestions would be appreciated.
It looks like you have not copied the Pictures to your Computer while importing.You might have selected "ADD" while importing.
Please reconnect the SD card and copy the Pictures to your Computer.
Then reconnect those pictures in Lightroom on your computer.refer link below
In future always select Copy/Move to import from SD card
Hope that helps
