I second this suggestion. I'm specifically visiting the forums to see if there is a workaround to this issue.
I upload client photos and provide a password. It'd be valuable feature to allow us to create a collection from these password protected galleries and have them inherit the permissions of the collection, not their host gallery. It seems inefficient to both the user and Zenfolio's servers to upload the photo again.
Is there another way to accomplish this goal without uploading a separate instance of the image?
