the default files are located inside the application package.

In the application package,

Contents->Library Files Hipriority->000Images

the white file is 000
the black file is 001

I suggest that you change your programming rather than the files -
because there is a very good reason for them being this way round-

it means when the lighting desk programmer hits clear. this then brings up a white image when lighting intensity is brought up - what you would expect with a moving light or video projector.
if 000 is black, then nothing will appear.
default states should always do something visible.


but you can change the files inside the application package by changing black to 000 and white to 001.
