php - Why the image disappear when participating in the Facebook note builder you select the link to the image through Meta Code -

-

when share link website on facebook , don't find image selected desperate other users when share facebook link dosnt see 

<meta property="og:image:height" content="240"> <meta property="og:image:width" content="440">

i got permission error (403) when try access image directly. that´s reason why doesn´t show. after fixing that, refresh open graph tags in debugger: https://developers.facebook.com/tools/debug/

edit: og:image not image @ all. must absolute url picture.
