Images are the cornerstone of social media, and brands need to find ways to incorporate images into their content, Janet Johnson writes. But there's more to Web images than just jokey pictures of cats, she writes, noting that images can be used to inspire, convey your brand's personality and inform your audience. "People surfing the Web today are overloaded with so much information, that they are in a hurry to get through it all. So, what's the quickest way to absorb information? It is through the use of images," she writes.
