Floating images

[Saltire]

Hi folks,

Fairly simple query but im stumped on how to go about searching for it...

I have a table: <left column> <middle column> <right column>

in the left and right colums i want to have two 'image' menus (which will consist of 4 images in each menu) - they need to stay in the middle of the columns and the center of the columns all the time,but when the page is scrolled down,, they need to move with it.

What type of script would let me do this, and do you have any examples?
