I'm trying to set up a Twitter card for a website. I've the following meta tags:
<meta name="twitter:card" content="summary_large_image">
<meta name="twitter:title" content="My Title">
<meta name="twitter:description" content="My description">
<meta name="twitter:image" content="img/foo.png">
All seems fine. Strangely enough, the Twitter's card validator does not display the image. I've just read a lot of posts about this kind of issue but none of them worked for my case.
It seems that also LinkedIn sharings do have the same no-image problem.
How can I fix that?
