Pop Quiz: Guess the correct file type from the list

Pop quiz (related to this necro); tell me which ones of these thumbnails are photos, and which are videos:

Any chance of adding some sort of indicator to each one letting us be able to differentiate what file type it is? i.e. perhaps a standard triangle shape overlay on the thumb to indicate that clicking it will “play” a video file?

Just using DropBox as a random example, they add a small video length icon below video files:


p.s. I wasn’t sure whether this post belonged in this PreviewGenerator App category, or somewhere else, so I just chose the nearest match. Feel free to move it to a more appropriate category as needed.
