   6       MoinMoin - Random Banner
   7    Purpose : The purpose of this script is to link to another
   8    place with a banner, like a webring
   9 
  10    Inputs : Receives an URL of a csv file separated with semicolon
  11    with three fields :
  12    name of site;url site;url banner
  13 
  14      The second argument is the width of the banner
  15      The third argument is the height of the banner
  16 
  17    Output:  Shows the banner, when you move over the banner it shows
  18    the legend and finally when you click you are directed to the site.
  19 
  20    Examples :
  21    ||<tablestyle="text-align:center;width:100%"><<RandomBanner(http://servidor.slec.net/~igotam/anillo.txt)>>||
  22    will show any of the records on the file as a banner linking to the site.
  23 
  24    <<RandomBanner(http://servidor.slec.net/~igotam/anillo.txt,200,20)>>
  25    will show a random banner on 200x20 size, linking.

  27 A file containing the following lines worked for me.

  36    Side Notes :
  37    Alternate ways of doing this would include using ImageLink macro with
  38    RandomQuote :) .  I remembered that when I have just finished doing this.
  39    RandomBanner DOES NOT rely on those macros.
