usage: copy this script to images folder + doubleclick, or from command line:

 perl $SCRIPT [ options ] [ "path/to/readonly/images" ]

default options: (think bandwidth!)

 [--in-path=]"$INPATH"
         directory containing readonly image files
 --out-path="$OUTPATH"
         directory where generated html and image files go
 --shared-path="$JSPATH"
         relative to --out-path, where generated js, css, etc. goes
 --width=$SCREENW --height=$SCREENH
         estimated available screen size
 --pixels=$THUMBPX
         length of a thumbnail's long side
 --jpeg-quality=$JPEGQ
         jpeg quality (0..100)
 --nohtml          (default = generate --out-path/html/*.*)
         save disk space by NOT generating html file for each image
 --force-overwrite (default = skip existing files)
         (re)?generate all files
 --text-only       (default = generate all files)
         don't generate --out-path/(html|images|thumbs)/*.*
 --quiet           (default = verbose)
         suppress most messages to standard error

(options can be abbreviated, e.g. -o "slideshows/2006" -s "..")

/* my_PickFunc IS AUTOMATICALLY CALLED WHEN AN ITEM STARTS TO BE DRAGGED.
The following objects/properties are accessible from here:

- dd.e: current mouse event
- dd.e.property: access to a property of the current mouse event.
  Mostly requested properties:
  - dd.e.x: document-related x co-ordinate
  - dd.e.y: document-related y co-ord
  - dd.e.src: target of mouse event (not identical with the drag drop object itself).
  - dd.e.button: currently pressed mouse button. Left button: dd.e.button <= 1

- dd.obj: reference to currently dragged item.
- dd.obj.property: access to any property of that item.
- dd.obj.method(): for example dd.obj.resizeTo() or dd.obj.swapImage() .
  Mostly requested properties:
	- dd.obj.name: image name or layer ID passed to SET_DHTML();
	- dd.obj.x and dd.obj.y: co-ordinates;
	- dd.obj.w and dd.obj.h: size;
	- dd.obj.is_dragged: 1 while item is dragged, else 0;
	- dd.obj.is_resized: 1 while item is resized, i.e. if  or  is pressed, else 0
