I tried to find the way to make do the rollover image using Views but after searching and looking into many websites, it doesn't seem to have clear the instruction how to do it. So, here is what I did to make it work. First of all, you need to download and install Image URL Formatter here -> http://drupal.org/project/image_url_formatter
1. Create a new content with 2 image fields. The Regular image field and a Rollover image field.
