Really great line of development here, glad to see effort being out into the Plex Photos app! A primary reason I use Plex is for displaying personal photos and videos on the TV.
I’d gladly use it to backup photos and videos locally as well.
Some initial feedback: In basic testing I was not able to get images to load – they showed up in the bottom strip, but the photo pane just said “Failed to load image”. I can provide logs if any exists.
I also would mention the existing and long-standing issue of video playback freezing sporadically during mixed photo/video streaming on Fire TV Stick. See issue here: Photo library stops playing sporadically when videos are mixed in
Thanks for the developments, looking forward to some further testing!
