The above picture is a screenshot showing a former header picture I used for a short time on my Facebook Fan page. It helped me create the current one with the right dimensions and positions. As you can at top right, it comes from chadfullerton.com. Thanks Chad!
After I created the cover for Facebook, I took the same image and used it on Twitter. I had to adjust the size. It’s simple, Twitter tells you what size is best.
Then the challenge came.
