[TYPO3-templavoila] Proper use of the "Local Processing" option

[Daniel Rutzen]

In regards to a previous posting of mine from sept 24th, "TemplaVoila 
automatically sets "file.maxW" when using an image field" I would like
to use the "Local Processing" option to change one value in my DS.


I have a DS of a FCE. (see it here http://pastie.org/630190 )

Now, I only want to change only one thing, in line 47:

10.file.maxW = 200   TO  10.file.maxW = 250


What exactly would I need to enter in the 'local processing field', of 
the corresponding TO ?

Do I have to paste the WHOLE DS into it? Or just a bit? I can't seem to 
get it right ;-/
