Icon for files that cannot be displayed (Ente Photos)

[soer1i]

I wish Ente Photos would display clearly when an image has a format (eg. .DNG) that cannot be displayed on ente. Right now these images are displayed just black. I could imagine an icon with a crossed over eye to be displayed for images that cannot be rendered.

Example how this would help:
I searched for blurry images to clean up. My phone sometimes takes pictures on accident, which often times are almost black. I selected all black images and deleted them. Only later did I realized that some of these black images where RAW files.

An indicator for raw files would help. But I think an indicator for images that cannot rendered is even more important.
