Mouse over the image to see the tooltip. This is bit more elaborated tooltip than the tiny ones you sometimes see in the middle of the text if something needs to be further explained. This one can be handy if you need to add more than just a word or two. It is actually a hidden paragraph that becomes visible by means of an attribute when mousing over the image.
On a mobile phone you need to refresh the page to make the tooltip disappear. Alternatively, you may download the version where the tooltips have been disabled for phones. The pixel width has been set at 700px, which, if needed, may be changed in the 'mouseover' attribute.
