special pictures in responsive lightbox

Hi!
I use Responsive Lightbox 1.7.2 and want to use only Special Pictures.
For example in a productside like https://www.agoshop.at/shop/ago-quart-der-algen-und-moosentferner/ago-quart-50/ I have add Special Picture for the product. These Picture should be used in Responsive Lightbox 1.7.2. But I use also cross selling products at the end and these Pictures will also display in the Responsive Lightbox 1.7.2. So how can I use only the productpictures for the lightbox.
kindly regards.

kindly regards

Hey there,
