Rollover image swapping as a field I'm learning Drupal and I'm trying to create a field where I can upload 2 images and let one face into the other while I mouse over/ hover / rollover it. Then I eventually plan to make it into a views like one in Zappos where the user can see alternate views on mouse over.

I've looked up the other thread and found the Rollover filter on Drupal but I still don't know how to make that work. I need it as a field of a node so that I can display a view of all the related nodes.
I would set it up as a single image field with two values and then use https://drupal.org/project/custom_formatters to create a custom formator for that field and do a display hide/show with css or jquery.
