How to Sub no image with "No Image Availble"

Hi All

How can I substitute a "No Image Available" image for image that have broken link?
Trying to import image from outside source with address like example: A red car, Address is say <!--<a href="http://www.somewhereelse.com/details/product_images/red">http://www.somewhereelse.com/details/...</a> car.jpg.-->

But the link is broken somewhere and I would like to insert a "No Image Available" in it's place. Is there a way to do that threw the file manger or if I place that image on my site can I link to it .
