Footer in Lets Blog - how to get the pics stringed together over the whole side as a kind of gallery

Hello!
I´m wondering how to get the pics in my footer slider (which I´ve linked to my instagram account) large, stringed together horizontal over the whole page from left to right. Exactly the way, theme forest shows in the lets blog demo. Who could help? Currently the footer is like you see on my blog http://thirty-ehrlich.de/ It´s a wordpress account.

Thanks!
