delete picture

Hello.
Another future which I think should be implemented, is the possibility to delete an uploaded image on flickr, once the associated node is deleted inside drupal.
If a user uploads a sort of forbidden image, then the administrator can delete the node associated to that image, but it will still exist on the flickr server; althought it's marked as private and not visible to others than the owner of the account, this can still represent an issue (just think about something VERY illegal which could cause troubles to the owner of the flickr account aka the drupal admin)
I think that flickr's api can allow this
Regards
K.
