   7       MoinMoin - Random Banner
   8    Purpose : The purpose of this script is to link to another 
   9    place with a banner, like a webring
  10 
  11    Inputs : Receives an URL of a csv file separated with semicolon 
  12    with three fields :
  13    name of site;url site;url banner
  14 
  15      The second argument is the width of the banner
  16      The third argument is the height of the banner
  17 
  18    Output:  Shows the banner, when you move over the banner it shows 
  19    the legend and finally when you click you are directed to the site.
  20 
  21    Examples :
  22    ||<tablestyle="text-align:center;width:100%">[[RandomBanner(http://servidor.slec.net/~igotam/anillo.txt)]]||
  23    will show any of the records on the file as a banner linking to the site.
  24 
  25    [[RandomBanner(http://servidor.slec.net/~igotam/anillo.txt,200,20)]]
  26    will show a random banner on 200x20 size, linking.
  27 
  28 A file containing the following lines worked for me.

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