How to delete Samsung S5 unsupported photos?

[AC Question]

I have a Samsung S5 that I need to delete unsupported photos off of. How can I delete them?

Where can you see the unsupported photos? Gallery or file manager? If you know which folder they are stored, just open MyFiles app, and then go to the location, long-press the photos and choose Delete icon.
