NextGen Pro lightbox customization

I don’t like the way how the lightbox butttons are distributed while the lightbox is open. The visitor is forced to move the mouse from left to right and then on the right upper corner if he/she wants to close the lightbox. I’d like to know if it’s possible to customize the lightbox – to set it for closing just by clicking directly on the currently open photo – just like it is on this page: https://dusanovo.cz/opet-ondra-prosicky-opet-heralec-opet-dravci/
