Text link to lightbox with multiple images

I’m trying to create a link to screenshots on my company site.

What we want is to have a link saying ‘View screenshots’ – then the user clicks on this and a lightbox pops up, where they can scroll through various images.

I’ve contacted my theme support, but they say this isn’t possible with their current lightbox set up.

Are there any plugins available that would do this? I’ve tried ‘Lightbox Gallery’ but I don’t really want a gallery – just a text link with the lightbox opening from that.

Any help would be really appreciated. Thanks.
