How to 2 important things

[nibb]

I cannot seem to find this. They are 2 very simple things and I dont seem how to accomplish them.

The first one is how do I block or stop users from posting external images. My forum is full or linked pictures in external servers. First I dont want to steal bandwidth from other servers. Second it makes the site slower and the most important thing. Most pictures and links are removed with time which leaves all my boards with dead links and images.

I want users only to be able to use images uploaded to the server, not linked externally. I cannot find how to block this.

The second thing is that I have a blocked forums and I want to display the subject on them, but not allow visitors to see them. I see so many other vbulletin forums that have blocked forums and you can at least see the last topic and my forums the private forums doesnt let visitors do that.
