This was all discussed several years ago. If I remember correctly a copyright notice and personal responsibility statement were written for the TOS, but then edited out by people a lot smarter then me. However the premise is still very simple. If one wants to post any images to this site, they have to be a member. If they are a member they have to agree to the TOS. If they agree to what is stated in the TOS, then whatever is put there is legaly binding as long as it is spelled out carefully and in full detail.
