Premise: Images are getting larger and larger with the demand for better quality. They can now take several dozens megabytes of space and movies in 4K can take more that 200 gb of space.

Solution: A algorithm that can take a image of a given size and output a single unique number. That number is what is saved on the image file. When you open the file, the computer solves the algorithm backwards to get the original image.

Could this work, /sci/? If not, why?
