Unfortunately the OG image next to the liked or commented on pages isn't correct.
When I check the page with FB Debugger it shows the correct image.
This should show up an image of Kylie wearing a denim jacket. But instead when I like or comment on the page it's showing a different image (a much smaller image as well).
When I look in the source, it points to the correct image, but it just doesn't appear on your FB wall.
I had it all working correctly before, however there doesn't seem to be an option to turn off the plugin's OG data.
