JQuery Drupal 6

JQuery Drupal 6


I am working on a new Drupal 6 site, where the top of the homepage
content needs to be an image that is replaced everyday and has an auto-
fit size - depending on the middle column width and proportional
height.
I wonder:
(a) is there any similar implementation out there ?
(b) what Drupal 6 compatible modules are required ?
(c) any pro suggestions ?
Cheers,
Monti
