I try to make something that looks good (or at least doesn't look like random static) by running pictures I've taken through audio editing software. There are some extra steps that go into it to "trick" the program into importing the picture as if it were a sound file, making sure the header (information that tells your computer that this is a picture) doesn't get fucked with, and then exporting the data in a way that it will be saved as a picture and not an mp3 or something else.

On the rare occasion I do bring it up, I can literally watch people's eyes glaze over. Until I show them a picture

Edit: internet is really bad right now, will reply with an image when I can

Edit2: picture was too big at 7MB. Hopefully a screenshot of the picture doesn't look too bad
