what

I'm assuming you are asking if it is okay if you submit a photo of your high score/time of a minigame rather than a video? My personal answer is "no", but I'll let a mod make the actual call.

No, legitimacy is only verified through videos and do you know how good people are at photoshop lol? I mean seriously I had a friend link me a picture of some guy who photoshopped an impossible time that a TAS couldn't even do so generally no video is highly, highly, frowned upon.
