Button on slideshow

Hi,

I would like to add an ‘Info’ button to each of the images on the slideshow at the top of my homepage, like this (see the red rectangle). Each button should link to the appropriate image in this gallery. My understanding is that I need the AddToAny plugin for this, so I have installed that and chosen these settings (I assume I need to use the ‘universal button’, is that right?). However, nothing seems to happen after I click the green button to apply my changes. What am I doing wrong?

Also, where should I go to set the URL that each button should point to?

Thanks!!
