html - The image to show when a web page is shared in facebook -


i've web page , want share in facebook image shown not ok. in html code of web have: 

<link href="http://www.example.com/img/logo2.png" rel="image_src" />

in options select image, there other images, not logo2.png i've tried delete facebook cache facebook debugger, result same.

edit:

if add ?v=1 end url when share it, logo option shown. means facebook debugger not deleting cache. also, want logo image first option.

can me?

solved:

<!-- facebook tags --> <meta property="og:image" content="http://www.example.com/img/logo.png"/> <meta property="og:url" content="http://example.com">    <meta property="og:title" content="portfolio | web">     <meta property="og:description" content="portfolio">

i think may using wrong tag. haven't done in while, believe should <meta tag property="og:image" , content set image. following (really old) question addresses issue/conforms remember: how facebook sharer select images , other metadata when sharing url?

let me know if works :)
