/*It looks through the document for any “img” or “input” tags with a class of “ro”. The rollover image needs to be named the same as the normal image but with “_o” at the end. For example, the rollover image for “image.gif” will be “image_o.gif”. After finding all the image tags, the script preloads all of the rollover images and ads the “mouseover” and “mouseout” events.*/
