Posting display.captureScreen( true ) to facebook

Is there a way to post the results from display.captureScreen( true ) to Facebook? I can post photos to Facebook without a problem, but I can’t figure out a way to get a screen capture onto Facebook. Below is the code (that works) for posting to Facebook.

local attachment = {         message = "I need help! Do you know the name of this puzzle in The Phrase Game?",         source = { baseDir=system.ResourceDirectory, filename="myImage.jpg", type="image" }     }     facebook.request( "me/photos", "POST", attachment )  end

I finally figured it out. I was saving my screenshots into the wrong directory. Moderators, please feel free to delete this post.
