* method rndImage is used to generate random images for the left and right hand columns on the sait.ca website. 
* method rndImage2 is used to generate random banners for the masthead on the sait.ca website. 
* both methods are included as to generate multiple sets of random images on the same page.
* Comments for both functions are only present in rndImage()
