Well for the "contribute test images" part, I'm not a photographer. I
have a good enough Canon camera and I can try to shoot some objects
with RAW on request though, but I won't guarantee the art quality for
these. Though you'll say that's not the purpose of this test set
anyway. :P

For the rest, yes, I can help organize, host if necessary, put up a
small website (nothing fancy, I'm not really into web UI design) or
something.
Also we should probably broaden the user list to encompass other FLOSS
graphics projects which would also be interested and can provide user
input and well as contribute photos. I don't think it should stay a
GIMP-only project.
As for gathering user input for instance, if every potential
interested project (GIMP, ImageMagick, Krita, G'Mic... are the ones
I'd think without much searching) would make a blog post to ask user
input and later user raw photos once we got the input, we could have a
usable test image set in no times (which can anyway always improve
with time and more user input).

I think the first step would be a small simple page to present the
project with a way to contact us. We could have a basic survey there
"what are you looking for when you want test image and for what
purpose?". I can do such a thing.
Then we can redirect people to this URI anytime, and ask projects to
do blog posts. Because staying email-only is a way to have the project
end up in limbo with time passing.

Then at some point, we go to the "gathering step" where we ask users
to send raw photos, ask them to accept the licensing (I would agree
with CC by and CC by-sa personally), and ask them to get the explicit
agreement of the model (maybe with a written agreement scan even?).
And of course we could present what we already have.

For the decisions on exact contents, I would let any of you in charge
though, since I am not the best fit to decide. My main purpose here is
to improve Free Software and Graphics environment. :-)
