I'm using SV pro 2 which is a plugin for WordPress. The xml file is dynamically generated via php. Below is the code for it.
Each image in the gallery with its corresponding caption should go to a page within the website when the caption is clicked. How do I add those links since the xml is dynamically generated? The admin for WP allows me to add images and provide alt text / title text which serves as the caption.

Thanks
