Can I delete images from Pictures folder? Are they redundant? I have several gigabyte of images/photos in my Pictures folder on my Mac.
I also have the Photos Library and iPhotos Library bundles. I believe all my images/photos would have been imported into the these two libraries.

Does that mean that I can delete all my images/photos from the Pictures folder?
Normally the photos have to be imported to one or the other via drag and drop or the import button. To be on the safe side import some of the photos into the photo application. If they are duplicates you will receive a popup stating that the files are the same
