The size of an image in inches or centimeters is unimportant. What size was it in pixels, and what was the color depth? That's what the computers have to struggle with. For that matter, Wikipedia's computer has already done the struggling. If you click on "More Details" you will find the image available in many resolutions, from 161 x 240 pixels to 7479 x 11,146 pixels with five more resolutions in between.
(Guess who's been using Wikimedia Commons lately.)
