I've made ​​some image enhanced, where I've come up with some small images. It's very simple. I put 4 image clean together to lower the amount of connections and employ css to ensure that they're in position.
But there comes an "Error/Status Code: " when attemping to retrieve image very first time, however succeed the 2nd time. Scroll lower to request 21, here you will see more details as needed.
