With screen resolutions (finally!) going up again, it might be, imho ^_^, time, to think about upping the pic size limit from 1000px per size. It seems so...limiting...so...last decade! 
At work I'm stuck on an awful low rez screen, and anything much over the 1000 limit causes me to have to scroll, and I know others are probably in that same boat, but meh...it's an ancient 17" LCD. I'd gladly put up with a bit of scrolling at work if it meant a better viewing experience elsewhere.
Most extremely low end laptops and screens from the past 5 years and newer are at least 1366 px wide. Most modern desktop LCD screens are 1920x1080 or at least 1600x900 (inexpensive small ones).
Imho, should consider upping the max image rez to 1280 per side, or perhaps 1600 (but 1600 might be annoying for some laptop users). (The reason for 1280 instead of 1366 is to allow for border room in the browser).
Additional food for thought: There are plugins/styles for Chrome and Firefox to allow large images to be auto resized to fit well on pages, as well.
(Wordpress is notorious for people complaining about large images!)
Anyway, thanks for the consideration, just a thought. =p
