How to add a (external) link in each picture?

I have a slideshow. Each slide is a node. I want to add a link (external link) to each slide (1 slide = 1 link) but I don't know how.

I try to add the link with a personal field in the node. In Views, I choose "REWRITE RESULTS" (in Views) of my Image and "Output this field as a link" (and add [personal_fiel]). But javascript doesn't work anymore.

Help me please!
