You see them online everyday.
"Grumpy Cat" or "Most Interesting Man in the World". The pictures are the same but the wording is different.
These images are called memes. The official definition is "a humorous image, video, piece of text, etc. that is copied (often with slight variations) and spread rapidly by Internet users."
Pictures add interest to your Twitter, Facebook and Instagram posts so why not use these occasionally, to deliver your message?
If you’re extra creative, you could even upload your own picture and just change the wording each week.
