Not working images loaded with little html changes

[Bhargav(Bunty)]

Can you look at here once. http://codepen.io/bhargavbhandari90/pen/BRPQGg/

I made changes on html and changed css according to it.

I copied from here : http://codepen.io/desandro/pen/RPKgEN ( Working fine here )

Why it is not working with my structure? Am I missing something?

Looks like your images are behind permission

Thanks @desandro
for looking into this. I manage to solve the issue. Actually it was not an issue. After exploring some options, I was able to resolve my problem.

So closing this.
