Photos file locations in MacOS Big Sur 11.5.2
I was using a website that wanted me to upload a photo I had on my Mac; clicking the UPLOAD button opened a Finder window to navigate to the individual photo and select it for upload. But I couldn't do this (as described in 2nd paragraph). My workaround was to open the Photos app, drag the desired photo into an open Finder window where I could find it later, then start over on the website, now able to get to the photo I wanted in its new location.
Later, poking around in Finder, I see that I can get as far as Username>Pictures>Photos Library, but Photos Library isn't a real folder, it just opens the Photos app to continue the search for an individual picture.
Is there any way to navigate to individual pictures within Finder? I'd like a better way to deal with the situation described in the first paragraph above.
