Example, a photo sharing site among students in a school.

CCK fields

- image
- title

- description
- whoisthere (a tag field to put who is/are inside the photo)

- - -

The requirements:

- any student who can log in the system can update "description" and "whoisthere", revisions are kept
- only the one who upload the photo (node creator) can update "title"
- no one can change the "image", of course, delete the whole node and re-upload is ok

- - -

I tried "Content Permissions" in CCK. However, if the "edit title" permission is disabled for "authenticated user", no title can be input when creating a new photo. I could not find a permission column for "content creator".

Please advise. Thanks ~
