It seems like there would be a fairly large number of Drupal 6 websites with user pictures that will need to be migrated to Drupal 7 at some point and that the difficulty of migration might be keeping some sites from migrating.
There are various posts here and there about the code needed to migrate user photos but this may be daunting to some users. Would it be difficult to create a module that the user could configure with source and target directories using the configuration menu and that would then perform the migration, so that user could avoid getting into Drupal's internals?
It would also be nice if drush could be used for this migration, but the solution above would probably be accessible to more users.
I'm not a developer, so creating and maintaining a module seems to be more than I could commit to, but I'm wondering whether this would be easy for someone with more experience.
