Hey Antonio,
glad to hear that you managed to get it to work!
I will look into both areas and try to make the image overlay gallery more flexible. You mentioned the “gallery” project format – indeed I recommend you to try out that one as well, because initially I intended that format specifically for displaying several images in one project with greater degree of control; and if you save the gallery project in “large” size, the image gallery will be almost as big as the popup overlay images from “image”-format projects.
Sincerely,
