I agree, which is why I called them horrible.
UA-checking scripts also can't tell whether I've disabled JavaScript or
image loading, so even getting the agent right is of limited use.

Can JavaScript tell whether image loading has been enabled? Is suspect
(without having checked) that the navigator.mimeTypes[] property includes
image types even when their loading has been disabled. A method analogous
to navigator.javaEnabled() would be useful.
