Rename image upon upload with MD5 hash of the file

I don't believe this functionality is available in either the Drupal 5 or 6 version of the module. Development has stopped on the Drupal 5 version though, so this feature will not be added there. I'm moving this to a feature request for Drupal 6 FileField (which would also give it to ImageField).

This will not be added. FileField is essentially discontinued since it has been integrated into Drupal core.

Note that this might be possible with FileField Paths, and it would be the best place to look for this functionality in the future (the maintainer has already started work on a D7 version also).
