There is also a way to use images as tooltips, if JavaScript is enabled ....

Dog breeds ( as per FCI classification )

Sheepdogs and Cattledogs (except Swiss Cattledogs) Pinscher and Schnauzer - Molossians and Swiss Mountain and Cattle dogs Terriers Dachshunds Spitz and primitive types Scenthounds and related breeds Pointing Dogs Retrievers - Flushing Dogs - Water Dogs Companion and Toy Dogs Sighthounds

 A generic picture of a dog that belongs to the group

The tooltip images might be useful for example
to a reader who does not quite know the English words
for the breeds but recognizes breed types from images.

The example above uses JavaScript techniques ....

code for onmouseover event changes
a default image to a specific image,
illustrating the breed, and onmouseout code
switches back to the default image.
