Web page image

Hello,

I’m new to WordPress and I’m not a websites developer. I need help with the image of my web page. It’s the one I have on the header and also if I click on it, it leads me to the wed page itself. But when I paste the link on LikedIn or Facebook, the image does not appear, instead, a blank space gets there. If I go to media, the image is attached to home, but that does not solve the problem.

What am I missing?! Thanks a lot!!

This is my wed page: http://homingwordstranslations.com/
