I have photos that are offline. I went to library and selected find missing photos and hundreds were pulled up. I clicked on ? and hit locate. It takes me to several pictures on the computer. Is there a way to restore all the pictures quickly or do I have to do this one by one? How do I stop this from happening?
Check your Folders pane in the Library.
If you have folders that are marked as missing "?", you need to fix them before you attempt to fix individual images.
Why are the images Off Line? Are they on an external drive that is not connected to your system anymore or on an external that has failed?
