There’s no debating the fact that including images on your website or mobile app draws the interest of users and leads to stronger engagement. For example, posts that include images produce 650 percent higher engagement than text-only posts, according to a WebDAM infographic. Use of attention-grabbing images is only going to grow. Consider that by 2018, 84 percent of communication will be visual, the infographic noted.

As the number of images and videos on a website continue to grow, slower load times and thus a negative user experience are both growing concerns for any company. An article this summer in The Fiscal Times, citing Internet data measurement company HTTP Archive, noted that the average website is now 2.1 MB in size, compared to 1.5 MB two years ago. And one of the biggest reasons for this growth is the addition of content such as videos and engaging images designed to drive more traffic to the site.

Images are a major part of any modern website. Images nowadays account to more than 60% of a website's total bandwidth. This is even more pronounced when dealing with cutting-edge web design. On an image rich social website employing a Pinterest-like layout, this number can reach upward of 85% (!).
