First of all I wanted to say thanks for this great plugin!
It actually is working very good, but I'm experiencing one problem (not directly related to your plugin) and I don't know where to turn to solve this.
Every time I make a wordpress post it gets posted to twitter (thanks to your plugin). But I have made a further connection with facebook, twitter tweet gets posted on facebook wall as well.
My problem is that some posts on facebook wall conatin images but others don't, mostly they do though.
When I create post I always add images, and I don't understand why sometimes facebook wall contains images from wordpress post, but sometimes not.
