Linking description, not image

Hello there,

Is there a way to link the description or title. At the moment it´s just the image that is linking to an external site. I´m relatively new to the programming world so I´m kind of overwhelmed by the code and can´t quite figure out, where and how to edit the plugin. Every help would be very appreciated. 🙂

Thanks in advance.
