The old saying holds true: A picture is worth a thousand words. People respond to images -- literally, when it comes to social media. A post that includes a photo or a video is much more likely to be noticed than pure text. Post pictures that tell your professional story -- for example, an image of you presenting at a conference or a screen showing the final version of a cloud-based service you've been working on --along with appropriate pictures that tell your personal story. Savvy use of photos is especially important given their prominence in your timeline and news feed, and Facebook recently enabled the use of photos in comments. Facebook offers some tips for the best use of photos.
