This album shows pictures with a long description. 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 'Maximum # visible text lines below image' is 4. If the caption contains more lines you see 3 dots in the lower right corner an you can scroll to the other text lines. To prevent scrolling, make the value 0, but in that case a larger part of the image is covered with text lines.
