Copying Photo files to Dropbox
I have hundreds of still photo files and dozens of video files in Photos that I want to copy to Dropbox so that a friend can access/download them from there.
What are the best steps to do this on my iMac?
I've searched here and can't find a clear combination of 1) select many files in Photos at once for copying/export AND ensure they're original size once they get to Dropbox.
Any help appreciated. Thanks. :)
