Is anyone else struggling with this??

Does anyone else have this problem?

You go to Spacehey CSS preview so that you can create your custom layout whilst being able to see how it looks like in real time. Your satisfied with the result, despite it still being a wip. 

You put the code in your actual Spacehey profile and it looks just the same as it did in CSS preview...

except for the fact that instead of the picture you selected, your background (the one behind your profile mind you, not the one on the profile) is simply white.

I've tried a few different codes and I still haven't found a solution. If you know a way to fix for this please tell me in the comment section. (btw I'm using imgur for the image link incase that's important)
