using a combo box to change a cells bg image

[mr_burns]

hi,

i have in the past been able to change a table background colour when
the cursor rolls over it, i would assume it is quite similar to
changing the background image.

what i want to do is to have a combo box with options and when one of
those options is selected, it changes the background image assigned to
a cell of a tables. is this possible?? if so, could somebody please
give me a simple example or direct me to a page that would explain
this. thanks
