    Place the URL of an RSS feed in the $file variable. 
        
       The $rss_channel array will be filled with data from the feed, 
       every RSS feed is different by by and large it should contain: 
        
       Array { 
           [TITLE] = feed title 
           [DESCRIPTION] = feed description 
           [LINK] = link to their website 
            
           [IMAGE] = Array { 
                       [URL] = url of image 
                       [DESCRIPTION] = alt text of image
