Twitter cards approved not work


Excuse my bad english
My twitter Cards are not displayed for my site
My Twitter card is approved, I received the email.
For twitter @demilune22

When I test the Card Validator is OK, but if I tweet my articles “Twitter cards” does not appear, just the title and the link to the article.
I tried with


<meta name="twitter:card" content="summary_large_image" />
<meta name="twitter:site" content="@demilune22" />
<meta name="twitter:creator" content="@demilune22" />
<meta name="twitter:url" content="" />
<meta name="twitter:title" content="Indiana Jones par Disney" />
<meta name="twitter:domain" content="">
<meta name="twitter:description" content="En Octobre 2012 la firme Disney à racheté le studio LucasFilm à Georges Lucas et à immédiatement annoncé la mise en production d'un nouvea ..." />
<meta name="twitter:image:src" content="" />
