Automatic image renaming based on title

Question

Is there a plugin or a "hack" that can help me do this? I have spent hours try to figure this out so I would greatly appreciate nay help. I have WP 3.1 running php5 Thanks!

eg.: postitle_image-ID.jpg

Answer 1

Hook into the filter 'sanitize_file_name'. See my plugin Germanix URL for a working example.

A plugin doing this is Rename Media.

Answer 2

There is also Media File Renamer, and it does a bit more than Rename Media.
