You know how some of those websites have when you hover over a link or a term a small grouping of text shows? Sometimes an image?

How can I get an image to show?

Also, is it possible to limit it to a onmouseover ?

There's a few ways this could be done, all depending on how it needs to behave and be positioned. There's both JS and CSS methods that I can think of.

Do you have an example of the kind you're thinking of?

Currently no. :[

I am trying to get this to work in a blog, that doesn't allow us to modify the code, but we can use spans, and a names, etc.
