How to display child images in slider panes

i want to show child images in slide pane. so finally the user doesn't have to go to product page at all.
and on clicking of child images, the zoom box opens for large image.

There is no option for that and the modification is not just one line to change.
For that, you will have to edit the file "listing_img_desc" as I think that you're using the item box layout "image and description" and add some custom code there. You would first need to load the images of the product before you would be able to display them.
