I should add: I have not researched if the above idea is even a viable
option. I know I can easily add an input field to the settings page,
and it's simple enough to get and input an attachment id ... Just was
curious if there's a more elegant solution.

I really wish WP blogs had a "blog image" upload field by default.
Seems like it could be helpful, esp. for a multisite install.
