As discussed during Office Hours, it looks like this should work and there might be a bug on our side. Can you create a support ticket here so we can take a closer look?
Hi, I have a similar problem. I just want to display a gallery of images (images are loaded via external links, just like the author of this thread) - but from an internal variable. I added the Image Slider element, connected the dynamic collection from the variable, but the images are not displayed in the Slider… Could this be my mistake in the settings? Would you please look at the screenshot
