Hi,
Within the image gallery you can either display a caption and description overlaid on top of the images or below the images either by hovering over them or setting it to always display. However, if you set a popup to show up on click, it will just show the image without showing the caption or the description. This seems a bit counterintuitive to me, especially since it can be difficult to effectively display longer descriptions without opening them in a popup.
I'd like to request the ability to toggle showing both the caption and the description within the popup window when a popup is activated, so that not only the image is shown but the important written info regarding the image and what it means. I believe that this will help our image galleries become more effective when it comes to directing visitors to external links. @Fouita @abdelhay
