I want to create a code that allows you to download an image you have saved as a save-code to your computer as a gif, png, or something else supported, but not as a snap! save code for a specific project,
so it can be an actual file on your computer,
but I don't know how any of these work.
Can someone tell me how any standard image file works so I can convert it into binary or whatever, but in the right way?
