// Global Variables

/* About Global Variables

   This image replacement script assumes a the existence of a standard image naming convention
   for all over/out state images.
   
   For example, all out state images are named as <descriptive name>_up.<extension>, and all
   over state images are <descriptive name>_over.<extension>.
   
   imageOverSuffix and imageOutSuffix represent the standard nomenclature chosen for the site.
   
   imageReplace receives a target object (typically passed using 'this'), an action (either 'over' or 'out'),
   and an exclusionObj (which represents an object to examine if there is a situation where the image replace
   should not occur).
