I tried google for help on this and it seems to be a bug in chrome but I still can't find a solution. The crazy thing is that it works perfectly in firefox.

Here is the css code
Code:
.container-image {
background-image: url('http://easource.com/wp-content/uploads/2014/07/traphouse4.jpg');

background-attachment: fixed;
background-position: -33.4% 0%;
You can see how it looks on http://easource.com

Also, I tried removing the background-position but still doesn't work.
