Greyed out photo icon
I have a 2018 MacBook with an external HD that had my photos app and all my photos on. I upgraded my macbook with a new larger HD and wanted to move my photos back to the macbook. After moving everything I tried to access my photos via a web browser ( so I could attach photos to my web site) and my photos app appears greyed out. I know my photos are there because I can access them via the app that is on my desktop but, just can't see them when I use the browser.
Any ideas why I can't get to my photos app through my web browser?
MacBook Pro 13″, macOS 11.2
