An 8 megapixel camera can turn out images that are 3264px x 2448px. That smart phone in your pocket probably has something like an eight megapixel camera in it. Google wants their users to have a good experience, so sites that are slow are ranked a little lower than similar sites that are faster. Page speed is one of the things considered by Google when they determine page ranking.
This is especially concerning for someone loading our site on their cellphone using their cell data connnection instead of wireless. We have a fast internet connection here on campus so even very large images will load fairly quickly, but not everyone who looks at our sites will have as good of a connection.

Your end user still has to download all of that data, that makes the page load more slowly. The file size of your images matters.Ĭhanging the pixel dimensions an image displays at in the HTML doesn't change the actual file size, it doesn't change how many kilobytes or megabytes it is. Image one is a little bit wider than the page body width, image two is massively bigger than the page body width. On larger than the body width will be scaled down to fit in the page if you don't specify a width for them. On webpages image files can be set to display larger or smaller than their actual pixel dimensions. The file size of image two is 47 times larger than image one. The pixel dimensions of image two is seven and a half times larger than image one.
