You can provide a link below the slider. Below each slide you can find Link the slide to: input field. You need to put the URL here. Thank you.
This is actually only true for static post slides, and not dynamic post slides (at least in the free version).
But – there is a simple workaround to make the whole image act as a link to its post on dynamic slides –
In the edit page of the dynamic slide, add a text layer with these parameteres:
Dimensions: 100×100%
Position: X:0 Y:0
Padding: 0px
Transparent: 100%
Border: None
Radius: 0px
Shadow: (empty)
This will simply add an empty, invisible text layer that covers the whole slide. And since the text layers act as links to the post, clicking anywhere in the slide will link to its post.
