But that won't work if you want a fallback position.

Like say my parent theme has header.jpg, and I only want to link to
the child's header.jpg if the child actually *has* a header.jpg. Won't

Using the is_child_theme() function in 3.0 will let you know if you're
running a child theme or not, allowing you to bypass some of that
check if you're not. Bit faster.
