invert only images

[duptabuser]

This is not an issue, but an option I would like to have.
Reason why (which might be the case for others as well, I guess):
. I'm using the global system inversion win&+
. So with FFIC I can reinvert temporarily to see images,
. But everything else is burning my eyes
Therefore
by having the option of inverting ONLY images, I would have a double inversion (with the win&+), for them (that is 0-inversion), and the single inversion from win&+ for everything else.

This looks like a useful option to have. I think it could be added to the next release.
