If your images are not working with this plugin please regenerate thumbnail

Sometimes after you install this plugin, you will see that many images that you previously stored had stopped showing full size, in this case you should regenerate thumbnails. This plugin: https://www.ads-software.com/plugins/regenerate-thumbnails/ will help you solve this issue.

This happens because once you propagate images with non scaled link on the newer images, the old images sometimes get left behind. This is the solution to this problem.
