Think about how the grayscale algorithm works. Basically, if you know the luminance of anything visual (e.g., a small image, a letter), you can replace a pixel with that visual element in a similar way to create a collage image. Try implementing this. You’ll need 256 visual elements of increasing lightness, all of the same size. You can create a collage by replacing each pixel in the original image with one of these visual elements.

This is a complex problem. To avoid passing in 256 unique arguments into a function, an array was used instead. Additionally you will find “createGrayscaleArray” and “makeGrayscaleAmnt” functions included to turn any one image into an array of 256 grayscale images.

When a program contains a global variable and a local variable with the same name, the global variable takes precedence when its function is called.
