Height attribute (100%) problems

I have a central table that has 3 cells extending the height of the browser
window. The two outer cells have an image whose size is also set to 100% to
give the effect of a shadow to the central cell. Everything works well in IE
but in NS (7.1) the left shadow does not extend to 100% although the right
shadow does? I know that the height tag is not especially well supported but if
one shadow image works, why doesn't the other? The site is www.loop360.co.uk.

100% height for an image is not going to work on most browsers, because
they think that 100% means 100% of the image real size, not 100% of the
container of the image.
Why not use a repeating backround image instead. (if you want to keep
the gradient effect, leave your original image on top (not as a
background), and then use a background image that will seamlessly blend
with the bottom of your original image...
