I'm trying to improve my website which you can find here :  Here .

As you can see, you can decide the image format between 3 options: Fit (will fit the screen), Normal (Normal size image) or Full (yeah you know). My problem is that i want to make the Full (and the normal when it occurs) image scrollable.

I tried to use the makescrollable function but it did not work. I found a website using full background scrollable picture, exactly as i want -> Here

The original project can be find here

Here is my code, i think i have a issue on the Makescrollable function, with the wrong $(****).

If you have any idea, you would save me :)

& Please excuse my poor English, i'm a french young student!

Have a good day & thank you by advance!
