Hello. I have noticed the photos viewer app from W10M has some problems, specifically, there are some file types that it will open but you can't zoom and move around. This happened to me during a presentation and it was quite annoying. Thus I started looking for an alternative, and I found Mikan Viewer. It works perfectly with those images too, and has a search function to help you find images which is quite useful. It works in continuum too 
Also it has just been updated, which fixed a bug that showed a white bar at the too of the screen in my phone.
A good app overall.
