How to scrape a "og:image"

I'm founding a lot of sites where the "post image" is only available on the meta name="og:image"
Is it posible to scrape this?

You have to use element attribute selector. Write it like this: "meta[name="og:image"]" and as attribute set the one that has images URL.

Thanks for your answer.
If i got it, i have to select "element attribute" as a Type, write meta[name="og:image"] on the selector... and I don't understand what do you mean as "attribute" that has images URL =P

Thanks for your help.

You have to find in page source code this meta element and find its attribute which contains URL.

For example: <meta name="og:image" src="image.com">

So as attribute you have to set src.

Oh i got it!!! Thank you very much!
