How can comuters store pictures when they can only use numbers?

Computers store pictures by converting images into a grid of tiny squares called pixels, where each pixel is represented by numerical values that correspond to colors. Typically, these numbers are stored in formats like RGB, where each color is defined by three values representing red, green, and blue intensities. This numerical representation allows computers to recreate the image visually when displayed on a screen. Ultimately, the combination of these numeric values forms the complete image.
