Why are you uploading large high resolution print resolution image to your web site if your web pages are 1720 px x 1080 px that is less then 2MP. Resolution is meaningless on the web all that is important is the number of Pixels. If your web pages are 1720px x 1080 you web image should be less the 1720px x 1080. Large image files will have to be scaled down in size to fit fin in your web page. Its a wast of time and resources to transfer large print size images across the web, It just lengthening the time it takes the display a web page.
