This album shows pictures with a long description. If the description requires more as 50% of the screen height, a vertical scroll bar is added. The index page shows the title below a thumbnail and the comment in the tooltip.
In this album is check-mark 'Prevent that the description overlaps the image' set and 'Fill box around the description and attach it to the image' cleared. It is not recommended to set the last check-mark, because in that case the caption width will be equal to the image width which gives mostly less space for the caption.
