Pulling the Wrong Featured Image from Homepage

Hey there,

I have the floating sidebar on my homepage and every time the ‘LIKE’ button is clicked its showing a random image from the site (http://i61.tinypic.com/2agp3eo.jpg) – How do I make it a set image or just something different from the one image it is right now?

Thanks in advance,
Kris
