Before the website went down, there was a way to look up the content if you knew the links where they were stored. But as far as I know, since then, the free previews have been disabled, so I haven't had luck getting to view the current images.
The last 'free preview' image that still works is https://tailheat.com/images/template/647.jpg
If anyone knows how or where the newer ones are now, please post an update. No need to use siterips if it still works.
