how to make a video file that corrupts every time it is downloaded. Do you guys understand what i mean? I want an image that gets even more cursed the more it is downloaded intentionally but i am not quite sure what kind of html data can be stored into an image to get the most similar to my proposition

malware can be embeded into an image or a video so therefore can we not embed something that corrupts the file more and more

Yes this is the only way, you could of course ask people to download an image and then post it and people to only download the latest which over time does accumulate compression errors (provided lossy compression is used) but that's not what OP is asking for. Even the whole virus thing would probably need consenting helpers since it's not really possible with your everyday imageformats so it would be more like a small program you download every time.

so idiot download picture the picture has some sort of software that checks if the image is the same as if it is when it was downloaded if the following statement is true then it turns it from 720p to 480p and continues decreasing in quality each time

it can, but the malware still needs to be executed from another source, you cant execute anything with just a pure jpeg

im not sure what youre asking, there is no way to force someone to degrade the image every time it gets saved, the best you could do is host the image on a website and just have a program that lowers the quality everytime it gets downloaded.

If you know the media player the downloader uses, you could potentially design a file that triggers a remote code execution exploit. There probably isn't any of those left for common video and image formats, though.
Besides, if you had an exploit like that, you could just sell it to your favorite three letter agency for six figures instead.
