SSL - Not all content secure

[Nashy]

I run a vBulletin site, and have an issue with security warnings due to the SSL on the site.

Users are getting browser messages about not all the content being secure, due to images users have posted on the forums that are linked to non https locations.

Is there a way I can stop this occurring without disallowing them to post their own pictures?

No, the only way to stop it is if you only allow people to post images that are on SSL sites

You got the same thing here when viewing the image thread/topic on https mode...
Other "costly" way is to redirect non-https image link into https one.

http://unsecure.freeimagehosting.cheap/image.jpg
into:
https://http.secure.img.reditector.safe/?imgurl=http://unsecure.freeimagehosting.cheap/image.jpg

Or something similar.

Edit: 'Redirect' is inaccurate, its more like what web-proxy doing

You wouldn't be able to do redirect as it'd be redircting to a HTTP site not HTTPS and you'll get the warning, you'd have to (on the server side script) manually get the file, then serve that file back to the client over HTTPS, which works out expensive in terms of bandwidth usage.

Replace linked images with thumbnails hosted on your website. Problem solved.

When the user clicks the thumbnail you can show the image using JS or just send the user to the corresponding website.
