Scrolling through Gallery

I just looked through some pictures on a webpage, where I could scroll vertically through a gallery of pictures and while scrolling popups with explaining texts would open and disappear after reaching the next picture.
Can this be done in Sparkle?

I managed to create a gallery, where a popup shows up for a (by mouse click in the gallery) selected picture, but it is not quite the same…

Without having seen what you have seen, we need a psychic.

But I think that’s not possible with Sparkle right now.
