We just released our latest stack Dealer.
Dealer presents a random image from a remote folder containing a selection of images.
Multiple Dealer stacks can be placed on a page.
Any dealer stacks on the page pointing at the same remote folder will never display the same image as another pointing at that folder.
While you will likely find many uses for the stack, our primary goal was to allow a huge folder of images from say a photographer, to be used to display a random selection from that folder of say a dozen, each time the page loads.
The idea was born following this forum thread: https://forums.realmacsoftware.com/t/random-or-daily-image-stack/19295/13
