Automatic hide tag for pics and links?

[erwin]

Hey everybody, is there anyone here that know, or is capable of building a mod that would do this?

I know there's already a [hide] tag but is it possible to do this automatic to certain things that are posted? like pictures, links etc....

It would be real cool if it's possible that only members can see the pictures and links posted, and not the visitors.

Visitors would have to register in order to see the posts....

Not sure if it's already done, but I searched around and couldn't find it

Kind regards, and I hope to get a reply!
