Good post.
While y'all work on a more comprehensive solution, individuals can do this
1. Download Firefox browser instead of Internet explorer
2. Install it
3. Go to Tools, Options, Web features
4. Either uncheck "load images" or leave it checked but also check "from originating site only"
That will stop linked photos from other sites from being loaded automatically.
Another choice in firefox is to right click on an offending picture and select "block images from" and that will block images from the linked site - someone mentioned somethingawful.com as an example.
