Hackerr

This application allows members to add notes to posts.

The application lets you add a new bookmark with a list of users and which has more built-in features.

This application makes it easier to run your site as full https and helps solve the problem of user posted http images. Displaying http images on a https page causes mixed content browser warnings and is a common reason why forums can't easily run as full https. 
When a user posts a link to an external image the application does the following:
- Checks if the user is posting a http url. If so it checks if there is a https version available (most popular image sharing sites have https support). If a https version is available then the image is simply rewritten to use the https version. This results in no proxy being used at all and many people could run this plugin in that mode completely if they didn't want to use the proxy component. This is the option that the IPS solution really misses.
- (Optional) If there is no https version available then the image is rewritten to point at a local script. This script gets the image in the background and serves it via https thus removing any mixed content warnings.
 
Requirements
Your site needs to be running with a https base url with a valid SSL certificate.
Your server must be able to make outbound libcurl requests via php to download images.
Use the sslimageproxy_check.php script in the tools folder to verify requirements before installing.
