//or they can be used to place a series of 3 flash animations with 3 replacement gifs, all picked at random



//1.  to place a single flash animation with replacement gif call this function, using this format, feel free to copy and paste:

//<script type="text/javascript" language="javascript">checkforFlash('graphics/flash/someFLASH.swf', #WIDTH, #HEIGHT, 'graphics/someIMAGE.gif')</script>



//2.  to place a series of 3 flash animations with replacement gifs call this function, using this format, feel free to copy and paste:

//*IMPORTANT:  if you only include one flash file in this function and leave the other two blank this

//function will not replace that single flash file with 3 random pics it will only do the first pic as a replacement

//<script type="text/javascript" language="javascript">checkFlash('graphics/flash/someFLASH1.swf', 'graphics/flash/someFLASH2.swf', 'graphics/flash/someFLASH3.swf', 'graphics/someIMAGE1.gif', 'graphics/someIMAGE2.gif', 'graphics/someIMAGE3.gif', #WIDTH, #HEIGHT);</script>
