	Usage:
	*******
	
	The function can be assigned to the onload event of an iframe.

	Arguments:
	**********
	
	- iframe_ids:
	  an array of iframe ids associated with iframes containing adtags
	  *or*
	  a string containing a single iframe id
	
	- iframe:
	  a reference to the iframe that triggers the function
	  (this iframe must have a unique id)
	  *or*
	  a string containing a unique id
	
	- do_ivw_count:
	  boolean value
	  If set to true, executes the function 'count_ivw' provided
	  this function is defined.
	  
	Please note:
	************
	
	- The function gets executed on reload of the master iframe,

	- In IE 5.0, iframes do not fire the onload event.
