Q: 

How long is Facebook caching the sharing thumbnails?

Hi guys,

How long is Facebook caching the sharing thumbnails? I've added a custom thumbnail for my page using:

<meta property="og:image" content="/path/to/my/image" />

But on pages I've already displayed before my image is not displayed => it is cached somewhere on FB servers.

Any ideas how to flush that cache or how long does it take once FB loads a new image?

Thanks!
