When opening an email from external people and pictures inside users are getting Authentication required prompt. What do we do to stop this from happening?

I would say have a look at the BODY field of the email. I am guessing that the EMAIL BODY contains links to HTML pages external to your envrionment. It is these external sources that require the authentication.
or is the mail encrypted?

The mail is not encrypted. And it is not just one email but, several.
Subject: Looks like you use a proxy server
There could be several causes for what you’re seeing, but the most likely one is that your organization uses a proxy server (e.g. MS ISA Server) to handle Internet browsing.
When the Notes client tries to display an HTML formatted e-mail message that contains references to external content (e.g. images on a public web server) it may try to retrieve those images for the user.
Typically, your IT department will have configured your web browser to use the corporate proxy server, and to authenticate automatically using your network login. But when the Notes client tries to retrieve some web content, it doesn’t have access to this info and so it fails. The “authentication required” prompt you see is probably triggered by your proxy server.
How to fix this? Try adjusting the Internet Browser setting in your current Location document to Internet Explorer or Notes with Internet Explorer and see if this makes a difference (might need to restart Notes after the change to be sure it takes effect).
You might also want to look into the “Format preference for incoming mail” setting in people’s person documents, though No Preference usually works best.
You can tell Notes what proxy server to use on the Basics tab of the Location document, but you can’t give it a name and password to log on with (at least not in the Notes R5 client I’m using).
Lastly, it’s worth checking what e-mails are causing this issue. AFAIK, it’s good practise to include any images within the MIME message being sent, rather than reference external content.
