Comment Access

If I'm missing this somewhere, feel free to let me know.

My gallery got spammed by an actual person (I'm assuming, because comments are CAPTCHA enabled?). Two of my albums are password protected. Is there anyway to disable comment access to the general public? I don't want to have folks register, in order to comment, though.

However, if I password protect my albums, yet folks can come in and comment spam, as well as see my pics — cuz when they view the comments, they can also see the pics (that are password protected) that are tied to the comments, then what's the point?

If an album is password protected, then add/view comments should not be accessible, along with the protected album(s).
