[jQuery] Trying to add/remove a class "when...."


Hey all.
I'm trying to add/remove a class and am having trouble. When I add the
new class, the color takes hold, but not the changing of the
background image.
The original CSS is defined as input[type="button"]{background-
image:....}
How do I remove a class that is defined like the one above? I tried
removeClass("input"), but that didn't work.
