At work, I often need to find the
og:image property of a web page.
My process used to be
cmd-opt-u to view source, then
cmd-F to search for the string
og:image, then select and copy the URL.
Then I made a simple bookmarklet to find the
og:image tag if there is one, and display the URL for copy and pasting.
