I know we already have the "Picture of the day" thread and I don´t know, if my idea is even possible, but on the Cate Blanchett board there is a thread, where every week a pic of Cate is suggested by the forum members (it´s called "Picture of the week") . The other members can vote for it and the pic, which wins is displayed (I think here is the problem).
There can be for example: "Cate (in our case Nicole) reading" and then 5 (or whatever number you want to choose) pics are suggested and then you can vote for them. So they have a "Theme of the Week" (there the list can be endless: from Nicole at the Oscars, to Nicole and Keith, to Nicole with glasses, elegant Nicole etc.)
There only the moderators or the admin (of course) can suggest a theme.
I don´t know if this idea is good for this board, but I think it´s quite good.
