Moving photos from MacBook download folder to desktop and Photos I would like to move photographs from a professional photographer to my desktop as well as into Photo. Please tell me how to do that.
Select all photos you want to move (in downloads folder in Finder), go to Edit menu-> cut. Go to desktop and in Finder, Edit menu-> paste.

For photos, Go to File -> import -> navigate to downloads and select using command-click or shift- click and hit review for import. Then finalise.
