Is it possible to zoom the pictures when you scroll wheel?

Good day! Wanted to embed the finished script zoom about the scroll wheel, but faced with the fact that when you click on the picture pop-up window appears with a picture, and then it is necessary to trigger the script scrolling. In the script pop up window put in the necessary class zoom to zoom in when you scroll the header of the hooked script, but in the end did not work. I understand not everything is easy and possible scrolling of the build in pop-up window?
File pop-up window fails to attach, attach a piece of code, they added this class zoom.

The website with the script increasing the wheel

window.JCCatalogElement.prototype.showMainPictPopup = function(e)
{
 var pictContent = ";

 pictContent = '<div style="text-align: center;"><img class="zoom" src="'+
this.currentImg.src+
 '" width="'+this.currentImg.width+'" height="'+this.currentImg.height+'" name=""></div>';
this.obPopupPict.setContent(pictContent);
this.obPopupPict.show();
 return BX.PreventDefault(e);
};
