大家好我正在使用Open Graph标签让g +（和facebook）从我的博客帖子中获取更大的图片。
因此对于元区域中的帖子，它有：
<meta property="og:image" content="http://www.gamingonlinux.com/uploads/articles/tagline_images/1779247106id3734gol.jpg"/>
<meta property="og:type" content="article">
<meta property="og:title" content="Update: Contagion Zombie FPS Game Still Coming To Linux, Work In Progress" />
<meta property="og:description" content="We let you know recently that the Source engine based zombie survival FPS game Contagion would have news about a Linux version soon. The developers have given a small hint about it now." />
<meta property="og:url" content="http://www.gamingonlinux.com/articles/update-contagion-zombie-fps-game-still-coming-to-linux-work-in-progress.3734" />
它在og：image标签中有正确的标签和大图片，但g +仍拒绝接收它。
我错过了什么吗？
