Text over Image. This is great for descriptions without the inconvenience of the standard browser tooltip, which disappears shortly after without giving much chance to read the text. This one stays for as long as you hold the mouse over it and disappears as soon as you move the mouse out. Also, it follows the cursor. It can be used for simple, short descriptions or notes, as well as for putting in huge amounts of information that people can read without having to go to other pages or taking lots of space or looks from the current page.
