Conditional logging

[Mushin]

Hello,

My app has lots of image files, and client requests for these images are
bloating up the access log a lot.

I was wondering if there is a way to log conditionally; for example, if
there is a request for an image file and it is processed with code 200,
don't bother logging it.  

Is this possible?

Thanks
