PrimeNumbersSmall.png(320 × 240 pixels, file size: 13 KB, MIME type: image/png)
Description English: Every pixel here represents a number in the range 1 to 76,800.

If the pixel is black, the number it represents is prime. If the pixel is white, that number is not prime.

So for example, the white pixel in the upper-left represents "1", which not prime. The next two black pixels to the right in the same row represent "2" and "3", which are prime.

For any pixel, the number it represents is given by

number = column + (row-1)*320

where column runs from 1 to 320, and row from 1 to 240.
