OK; this test can be skipped when -noimages is given,
either on the command-line, or via a variable in an intialisation file.

That's fine, when you give -noimages ,
but it may also skip the (perhaps useful) test when no image-related
option is given. That's not correct.

The diff is fine --- though I probably won't use it; since it's not
correct according to the above comments.
However it shows a way of achieving what you want, and the clear
description of the problem clears up any possible misrepresentation
of your intention.
I'll take a closer look at it.
