Recently I saw a unexpected visitor suddenly appearing on my footer. A unusual guest named smiley, yes really! As I was doing a regular check on browsershots.org to see how my website was displaying in all the main browsers I noticed a random gap after the footer with a small smiley face in the bottom left corner and sure enough I saw it for myself when I checked it out in my internet browser. What was causing the uninivited guest to appear? Read on to find our the cause of this weirdness!
