I am trying to make the process of adding an image to a slider as simple as possible for my client. To make my slider images work with a lightbox i have changed the html tag of the slide to an a tag and added the image attachment path to the URL section of the link option. While this works it is somewhat fiddly for my client as they have to seek out the image file path before attaching the image as a background to the slider.
I am trying to find a way for making the link address dynamic i.e. getting the background image url so i can simply show the client how to duplicate the slide and swap the background image without having to find the URL of the background image used.
any advice much appreciated.
