Hello, @TFS,
1. As you requested I have removed the site images from the topic reply and added them into the private content area of the topic.
2. I have checked your site and found that after the changes you made on the thumbnail cropping the images appear perfect. check this image: Under private content area (1).
The images appear full on the sidebar section. Please check back to your site after clearing the browser cache.
Regards 8Themes Team.
