High-res images are much larger and therefore take more data/time to load on a page. Depending on the type of image/industry/goal at hand you will want to use a low-res image to save on load times and data consumption.
Consider a few of these examples:
(1) Your audience is predominantly on smart phones or mobile devices, thus potentially using precious data to access your site, in this case high-res images would be doing your audience a disservice as they would be paying to load those large images.
(2) You have a photography based website offering free stock imagery or backgrounds, in this case you may want to use high-res images for your customers to access.
In the end, the cases where it is appropriate to use high-res images are few and far between, and most commonly a 72 DPI is sufficient for most web images. For more information see this article: http://www.creativebloq.com/graphic-design/what-is-dpi-image-resolution-7151567
