Wrong image for my article. Image is deleted and not even on my site?!



When I post my latest article on Twitter it is pulling a deleted image from my site. I have cleared all caches and deleted the image from my media gallery (on Wordpress) and yet it still shows the wrong, deleted image when I post it to Twitter? Any ideas on what I can do to fix this? I am using Twitter cards, but even when I shut that off I have the same issue.
The post is http://www.anxioustoddlers.com/wearsafe the image that incorrectly pops up is titled “Behaviors that Would Worry Even a Child Therapist.” (And the wrong image has a typo as well - lovely).
Any help would be so appreciated!
