  28         2005-08-06: 1.3.5-3 RB VS mode added 
  29                                by one step back or forward could be toggled through the selected slides
  30                                and the first and last one could be selected too
  31         2005-08-07 1.3.5-4 RB bug fixed for cgi-bin call. formatting of tables adjusted                    
  32         2005-08-13 1.3.5-5 RB code change from GET to POST
  33                               forms instead of link
  34                               toggle between webnail and image by click on image
  35                               alias (description) and exif_date added
  36                               this version needs Gallery2-1.3.5-7.py
  37         2005-08-31 1.3.5-6 RB html code changed into a function :-)
  38                                  some html bugs fixed too
  39                               instead of button text now images used (disabled buttons are grey color coded)
  40                               back link to callers page
  41                               whole page inserted into the common wiki page    
  42                               code clean up.

  45                               for the slideshow changed to a javascript player learned from Ricocheting
  46                               image preloading for webnails and fullimages because webspeed could be slow
  47                               slide show is really fast by this
  48                               default duration is 1000msec
  49                               (runs under 1.5.0 too)
  50         2005-11-01 1.3.5-9 RB output buttons changed to <SPAN id> text 
  51                               to all javascript functions added the prefix gallery2
  52                               some fixes on javascript code
  53                               controls separated.
