Now with many of us with the larger screens, larger images look much better to gain full impact, IMO. Most images present much better when viewed large so, it would be nice to have at least an option of viewing the images at their original made for web view. For my website, I now upload all images to 1200 pixels high - standard 3:2 photo in landscape means that it will be 1800 wide - which is well within the size for most modern large screens that many of us use nowadays. Even a 1000 x 1000 pixel image is starting to look quite small on my 2560 x 1440 pixel screen, an 800 pixel wide image is starting to look quite miniscule!
