child categories

[CyberShot]

I am having trouble getting the image when it is posted to a category that has a parent category. It works just fine if it is a top level category. I need to get the image this way

print apply_filters( 'taxonomy-images-queried-term-image', '' );

How can I get the image if the category the image is assigned to is set with a parent category? For example, I have a category called "Menu" and three categories are assigned to menu. "Breakfast", "Lunch", "Dinner". If I use the above code to try and get the images, nothing shows.
