Hi, I've downloaded the latest set of wikimedia dumps. I'm trying to understand where to find images within these dumps. I've studied the database schema and it seems to make sense, but then I take a single example such as:

http://en.wikipedia.org/wiki/File:Carrizo_2a.JPG

And I grep the dumps 'image', 'imagelinks', and 'page' looking for 'Carrizo_2a.JPG' and it's not found. I tried this on both the SQL and XML dumps.

Are these dumps not complete? Am I misunderstanding the structure?

Thanks in advance,
Keith
