Chris: A couple of questions. First, for solution a, it appears as
though I'd need to know the path to my config file to implement step 1.
I don't think that would work for me because if I knew that path, I
could figure out the image path. Please correct me if my assumption is
incorrect. For option b, this works great when running under
TurboGears, but I received an error on line 2 when I ran it in a bare
Python shell with the following error:
static_dir = pkg_resources.resource_filename("motion", "static")
ImportError: No module named motion
I used the previous suggestion offered by David and it is working fine
under both of the necessary scenarios. Dave, thanks for pointing me in
that direction.
