Why does background images for social networks important?

Does setting up cover image that much important when we are talking in terms of page load time. This is not an issue where you have high speed Internet connectivity but it creates problems where speed is not that much good around the world. And there it takes good amount of time to load any profile page.

A background or cover image can determine a lot of things for an individual or an organization. It tells your friends and followers what kind of interests you have and also tells a lot about your personality and nature.
