Impserve plugins Release 4 has now been added to
post #1 above. I've re-vamp the plugins to accomodate an all-in-one design; just set OPTION to your choice's name in certain plugins (edit it with any text editor).
No more swapping in and out of the plugins directory; just leave them there and edit the ones that alow different processing choices to be made i.e. ones with OPTION.
Note: You should restart impserve after editing plugins (.py) so as to ensure the revised copy is loaded into impserve and available to you!
