Under style gallery - new styles, they have kind of photo album with thumbnails at the bottom. After you drag a thumbnail to the big window, it rezise to a big picture and the previous photo is going back to the thumbnail gallery.

Anybody an idea how the made this, and how the code should look like.

Thanks :slight_smile:
