After some time fiddling today I mocked up a quick modular slider for one of my client's website. I wanted to theme the scrollbars so went ahead and picked up the the jQuery plugin called "jScrollPane" available here: http://jscrollpane.kelvinluck.com/. This simply did the trick and I was able to style the scrollbar with pictures. The only problem I am stumbling upon is that the scroll bar doesn't drag further than the middle, it does scroll horizontally the modules. Here is a quick jsFiddle to describe on my problem: http://jsfiddle.net/95fG6/. I am pretty sure that this is easily solvable and that I just have to set a parameter in the .js to make it work. But I am quick unfamiliar with the plugin therefore have no idea how to continue.
Thank you very much everyone! Thanks for taking your time!
