Beta version 1_107 has been uploaded to sourceforge.
CHANGES
A new flag ImageProcessorOptions.OVERWRITE_TARGET_FILES has been added to the script. When set to true IPP will always overwrite target files unless 'Save In Same Location' and 'Keep Original File' are checked. The default is false. You must edit the file with a text editor to change this flag. I may work this into the UI.
Enjoy.
