Your contribution cannot be approved because it does not follow the Utopian Rules.
Firstly MPV is a media player based on MPlayer and mplayer2. It supports a wide variety of video file formats, audio and video codecs, and subtitle types. Within this description, it does not state that the application has been optimised to support image and nothing within their documentation suggestions that it has and it's because of this, much of this contribution is not valid. Although I understand that when you open an image it closes instantly, this is because of the behaviour the developer has implemented for a when a video ends, as previously mentioned they have not created this application to be able to support images. Anything surrounding image support would be seen as a suggestion rather than a bug.
Also within your contribution, you use informal language such as " I didn't expect the lunatic behaviour from the amazing app." As per the Utopian Rules:
The writing style should be formal and informative.
I can also see that you haven't linked your GitHub account, this is against our rules. As per the Utopian Rules:
A contributor’s Utopian account must be connected to their GitHub account.
Finally, in the scenario where I believed everything else was valid the following rule has been broken, within the Utopian Rules it states submissions must refer to bugs on the latest released version of the application (not older versions). You didn't provide an application version number which means that I am unable to confirm if you're submission was tested on the latest version of the application. It is important that you provide details surrounding the application version number within your contribution. As per the Utopian Rules:
Submissions must Include information about the debugging technical environment such as Device, Operating System, Browser and Application versions used.
