protecting our pics

just wondered it there is away to protect our pics on here,as some other forums have this

yes I'm on another forum where you have to post a link and click on it to view. You must have a certain amount of posts to view and to even have an avatar and siggies. I've only been a member for a week or so so I'm unable to have these yet, which doesn't bother me, I've nothing to hide! i suppose even this will not stop someone intent on using them though but may put some stupid idiots like we have encountered off 🤔

yes think this would put everyones mind at least if the right hand button on our mouses where deactived
