If the image is 800 pixels by 600 pixels at 240 pixels per inch, then the image size is (800 / 240) by (600 / 240) or 31/3 by 21/2 inches.
50% of 1200 * 600 pixels
Printing a photograph in a newspaper and printing a photograph in an art book will require very different image resolutions. For the newspaper 100 pixels per inch is OK for the art book 600 or more. So if your image is 5 * 8 inches the newspaper picture should be 500 * 800 pixels or 400 000 pixels, the art book greater than 15 million pixels.
Ask your printer!You want to give a printer originals that are at least as highly resloved as their print process. Many print shops can print with resolutions of about 600 dpi (dots per inch). sou if you have more than 600 pixels per inch than you shoould be OK and not suffer too much degradation.
As it stands the question does not appear to make much sense. Anyway, 600 pixels = 60000% pixels, for what it is worth!
That means the your monitors resolution is 2400 pixels horizontally by 600 pixels vertically.
