Extract .SWF file from website

I need to extract the video located at : <[login to view URL]> will need ( i guess ...not sure) to be done by using a screen capture software because when i download the .swf file and convert to .avi the video works except for the picture i uploaded.? You'll notice on the website that at one point in the video you start to see pictures of a man on billboards, newspaper , etcc ( it's a picture i uploaded ).? when i download the .swf using a software then .swf file works except my picture is not there anymore hte image on the billboard, newspaper, etc... is now a black shadow
