For some reason, my specified thumbnail width and height aren't taking effect anymore. They did on a previous version of the plugin, but aren't anymore. I've tried re-saving the settings and regenerating thumbnails, but haven't had any luck.
You can see the widget here: http://demo.tandsgo.com/tsh/w4/2016/05/beware-the-shiny-showroom/
The thumbnails should be 75 x 75.
Any suggestions?
