I have some photos in the DCIM folder on a MicroSD card that normally lives in an Android phone. When I mount the card on my Macbook Pro using a USB card reader, Photos.app automatically launches. But the app doesn't seem to "see" that there are pictures inside the folder. I can access the pictures through the Finder (see screenshot), and of course I can manually import the pictures by dragging them from the Finder window into Photos, but I am wondering if there is some way I can point Photos.app to the directory where the photos are stored so that it can find them and import them on its own.

I believe this is a bug in the latest Photos app 1.3, which was released on Dec 8 2015.
It only imports pictures that has a filename such as DSCxxxx.JPG or IMG_xxxx.PNG. Also if you select "Import" from the menu and select your microsd card, all folders on that card are grayed out.
