Img show and follow cursor when mouseover hover

So, I want a gif (or the jpeg, but I’d prefer a .gif) to show and follow cursor when mouseover hover over the “vykort” link, down under the “Big south” section.
Now it’s a jpeg showing in the corner of the screen. It’s something, but not ideal at all. (edit: No, it does not. Seems like the scroll-and-change-the-background-interaction messed it up) Read only link down below.

But no success. At all.
