I imported my photos into LR but they are not showing up and they are not in the folder I pulled them from. Where could they have gone?
When you imported them did you select "Add" at the top of the import dialog window or was "Move" selected.
Item in Blue rectangle will Move images from original location to one you select, usually into the My Documents\Pictures folder on Windows and into the Pictures folder on a Mac for the Username that is logged in at that time.
Item in Red rectangle will leave images where they are and just Add them to the catalog.
But that doesn't solve the problem of them not showing up in the LR Library module.
