mySlide is a jquery plugin that will create a slideshow on your website using images from a particular google plus album. All you have to do is specify that google album in your javascript. You may also add a link url in the caption field of your image in the google+ albums interface. When you do that, the slideshow image will have a link to that URL. Hence when users click on that image in the slideshow, they will be redirected to your custom URL.
