What nodes use a picture from the /files directory?

We have a site with several hundred page nodes. If we need a picture in the page, we attach the picture to the page and then use html like: <img width="175" alt="ProductA" src="files/product1234.jpg" /> to show the picture. That works fine. If someone needs to use the same picture on a different page, they just put in the same code, and it works fine, although the picture is only "attached" to the first page.

Here's the problem though, the web manager wants to know exactly what pages actually use the picture "product1234.jpg". She says that was easy to do with the web site she used to have, with static pages and Dreamweaver - should could easily search a site and see what pages were using a particular picture.

I can't find any way within Drupal to do this at all - is there any way?

I played around with MyPHPAdmin and I can search for the picture, but the results aren't very useful, because it returns every version of every page that's ever used the picture.

Is there any rational way to search through the site and see where a particular image or other file from the /files directory is currently being used? Thanks! -Steve
