How do I add a picture to my post?

Hi again!! I recently tried to post the pic of my little baby bumpy btu everyone says they can't see it.
Does anyone know how I can add the pic to the post? Heeeeelp. . .lol. Thanks!

I open a separate window to my Facebook pictures and then click and drag whatever pic I want from my FB to the message window.

What works for me is download the pics to ur profile then u can copy it to your post.  to copy it you will have to open a second window and work back and forth.  Hope it works for you.  I had a hard time posting pics before i was told to try it.  Good luck
