Hi Thiago,
I agree to your point that changing css should be the ideal way to change
images.The problem was that when we changed image through css, we had to do
image.display = none and then provide a background to the anchor tags above
it with our images.. 

This caused the position of our image to be unfixed relative to the column
sizes. As a temporary measure we have put a script which first replaces the
existing t-sort-icon with a spacer.gif to remove out the existing sorting
image and then based on search for t.sort-column-ascending img and
t.sort-column-descending img(using prototype doubledollar), we change the
source with our images. 

This way, we have solved the problem that i highlighted in my post
yesterday(i.e how to avoid dependency of the images from grid).We will
surely look at a more standard css way to do it later.

Thanks

Sandeep
