Greetings,

i would like to use Pictures/Images instead of text when i hover my mouse over a e.g. button..

I found this site:

but i got no clues on how to work with it.

Is there any way simplier than this to add picture/image instead of text to a tooltip. I searched for some Jquery aswell but couldn't seem to figure it out.
