It seems that Publicize only works to Facebook and Tumblr if the post format is Standard. I made a post format of Image and it fails to post to Facebook or Tumblr, but it does post to Twitter successfully. I made a second post of Standard Format after the Image Format and the Standard Format posted to Facebook, Tumblr, and Twitter just fine (those are the only social connections I have made). So I do not believe it is a connection issue with Facebook or Tumblr.
Has anyone else noticed this?
The blog I need help with is blog.tom-brink.com.
