Here is my existing HTML, I want to add the ability to click on the image and link to another webpage or file, right now it just closes

here is the JQuery code:

Code:
(function(jQuery) {
	jQuery.fn.poptrox = function(options) {

		// Settings

			var settings = jQuery.extend({

					initialWidth:					200,				// Initial popup width
					initialHeight:					100,				// Initial popup height
					fadeSpeed:						300,				// Fade speed
					popupSpeed:						300,				// Popup (resize) speed
					overlayColor:					'#000000',			// Overlay color
					overlayOpacity:					0.75,				// Overlay opacity
					windowMargin:					50,					// Window margin size (in pixels; only comes into play when an image is larger than the viewport)
					isFixed:						false,				// If true, popup won't resize to fit images
					fixedWidth:						600,				// Fixed popup width (only used isFixed is true)
					fixedHeight:					400,				// Fixed popup height (only used if isFixed is true)
					easyClose:						true,				// If true, popup can be closed by clicking anywhere on the page
					usePopupLoader:					true,				// If true, show the loader
					usePopupCloser:					true,				// If true, show the closer button/link
					usePopupCaption:				true,				// If true, show the image caption
					popupClass:						'poptrox_popup',	// Popup class
					popupSelector:					null,				// (Advanced) Popup selector (use this if you want to replace the built-in popup)
					popupLoaderSelector:			'.loader',			// (Advanced) Loader selector
					popupCloserSelector:			'.closer',			// (Advanced) Closer selector
