Jigsaw puzzles

For the past few days I have been unable to post my finished puzzles to Facebook--is there a problem? Still unable to post puzzles to my Facebook page after downloading a new app- what is it that I am not doing? April24,2016---the problem above is still happening, I like to show my friends on Facebook my finished puzzles ,but they will not post. I have to post them to my Photoes and then post. Why?
