Computers store images broken up in to small pieces called pixels. It’s like a mosaic.
Each pixel is a different colour. Each colour has its own number. A number is stored for each pixel saying what colour that pixel is.
To display a picture the computer has to do a colour-by-number puzzle!
With symmetrical puzzles you only need half as many numbers to recover the original picture. Use symmetry to fill in the rest.
