just noticed when i "liked" on of my own post that the the posts thumbnail that shows on facebook is completely wrong. it used a thumbnail that i have on my sidebar widget. is there a fix for this?
Try it yourself: Enter this url: http://funny-pictures-blog.com/2011/05/08/lolpics-fail/ click on the NEW facebook like link below the photo and then check your facebook profile. you should now be getting a message that you liked this post and the "post thumbnail" is one of the images located in the blogs sidebar.
im using Version 4.0.1
