I publicize each new post on my Twitter feed and via that my Facebook page. When I post a picture in my photoblog, it appears as a thumbnail on Twitter, and then on Facebook. From this morning (Feb 11th), my Twitter feed is displaying my grvatar with each new blog post and NOT a thumbnail of my latest photograph. Why is this and how do I change it back? Thanks.
The blog I need help with is sonofthemorninglight.wordpress.com.
