problems with images with Publicize from wordpress to facebook

I’ve problems with the plugin publicize that don’t work right when I write a new post and i must to send this to facebook.

Before four months ago the plugin have done its work rightly .
Now I can view on facebook the articles only without the images

I’ve the same problems with rss graffiti that work well it send from my site (the same) the posts and the images to the others my pages on facebook

Sometimes if I change computer I can view three or four post with a standard image that is not included in the article

Is there a solution?

Thanks
