Gallery not working as desired

Hi, this seems a nice plugin, thanks for putting it out there 🙂

I have a gallery I am working on and the images should link to the article.

Instead of doing that though, the lighbox kicks in.

I can see that if I turn lightbox off on standalone paghes may help with this but is there another way ?

Many thanks !
