I'm using the conveyor belt to show some pictures, there is in the HTML a link for an outside link, to- http..- shown below:

leftrightslide[0]='<a href="http://"><img src="images/goldblack.jpg"></a>'

I would like instead to link on mouse over to a bigger size of the same picture- "images/goldblack.ipg"> - already shown in the conveyor belt but in smaller size. Any one knows how to do that? Thanks
