I like it very much the Pinbin.
It is a technology with great design.
Thank you.
However, I found that the display is different in IE8, IE9 and Chrome.
I want to fix this, but how is does not know.
In addition, I would like to center the entire corrections of Css does not know.

I am not done a lot of testing for IE since I am on Mac. There could be some differences but not anything major I guess.
