When I try to export my LR CC slideshow to PDF or JPEG, I receive a pop-up that reads:
"Some photos or videos in the slideshow point to sources that are currently unavailable. They will be omitted from the slideshow. To create a slideshow with omitted photos make sure all source files are available before exporting the slideshow."
I've tried creating the slideshow from a collection and from the catalog.
Does anyone know how to trace or track down the source files for the omitted photos?
The error message is symptomatic of 'Missing' photos (ie. the Catalog does not know their location), or- an external drive with the files may not be connected, or you are using Smart Previews only with the original files off-line.
