Image Proxy Settings
You only need to use these settings if you are setting up a proxy service for images. The typical reason for doing this is that your SharePoint environment runs under https and you have users sharing images from http sources.
Aurea Social can provide code for a proxy service that will take images from an http source and serve them as https to avoid users getting browser warnings about mixed security context.
Contact Aurea Social if you want to install this proxy. The installation instructions includes information on setting these values.
