Update CB field value after image is uploaded

We have created an image field in CB (cb_permitphoto) that allows users to upload a photo that is then used as part of a printable member permit. We would like to update the value of another CB field we have created (cb_activemember) once the user has uploaded a photo to cb_permitphoto.

Is this possible? Is it possible with Auto Action? If so, what action type and trigger(s) would we use?

And if not with Auto Action, is this achievable in another way within CB?

And would it be easier to do if we required moderator approval of the image? Does that give us more options for the ability to modify the other CB field?

You can use CB Auto Actions to act on field change and perform whatever action you like. See the below on how to do this.

So for example using the above you could use a Field action to change the value of a field based off another fields value being changed. As for what triggers to act on they are as follows with explanation of where they apply.

onAfterUserRegistration = frontend registration
onAfterNewUser = backend registration
onAfterUserUpdate = frontend edit
onAfterUpdateUser = backend edit

And would it be easier to do if we required moderator approval of the image? Does that give us more options for the ability to modify the other CB field?

No.
