401 redirect problem - How to avoid popup box and use 401 redirect ?

[Visitors]

Hi.

My problem is a little bit specific and I will try to explain.

I use coppermine script for website and I was setup some .htaccess commands because I charge memberships on my site. When someone try to see the picture he got announcement (popup box with text) that he can't access to that page and must return and go to sign up page. That's everything works fine for now, but, I know for 401 error with which I can redirect users from non-allowed pages to sign up page. I don't want anymore that popup box with text because it's non-productive, a lot of visitors close the page after that popup box announcement and because of that I want to send them right on sign up page with all instructions.

Is someone knows what I have to change to avoid popup box and start to use 401 redirect to some other page.

Everything is ok with .htaccess command, but something in coppermine script not allowed me to do that.

Thanks and sorry for my confusing english.

Best regards for all you guys.

Thanks again.
