Problems with buttons and overlays

Problems with buttons and overlays

Hi,

i've got two questions:

When i'm using the jquery overlay (jquery.overlay-1.0.1.min.js) i'd like to use a tooltip for the button whitch shows/hides my overlay - has anybody an idea how i could do this?

And when i try to add an image to a tooltip it doesn't work. How can i do this?

Thanks a lot!
