message of secured page

[Anon]

I have developed a website using php, cgi...

Tests on Internet Explorer were successfull. But tests on Netscape 6 and Netscape 4.7 give messages saying that my website "contains unsecured elements and asks me if I want to continue" whereas it has no crypted elements.

Can you explain me why the Netscape thinks that my pages have secured elements... whereas Internet explorer notices anything?

That message usually appears when you access the site over an SSL connection (HTTPS) and the page contains images sourced from a regular connection (HTTP).

Could it also be a javascript that's trying to do something that NS requires a key for?

I know placing a browser window outside the desk view causes an error in NS since the offending page needs 'permission' to do so..
