Can you help explain this:
but the old image is still being referenced in EasySocial when adding the link.
How are you adding or sharing the link? Are you using the Facebook Like or Share button, sharing directly on Facebook.com or using some tool within EasySocial?
Generally, Facebook will re-scan your page every 1-7 days to check for new Open Graph tags. That means old values can be cached. You can use the
Facebook Open Graph Debug Tool
to check how Facebook sees the page *and* have their cache updated immediately by hitting the "Fetch now" button after putting in a URL.
If the information in the Debug Tool shows correct, you should be good to go.
One thing to note is that Facebook doesn't allow changing some Open Graph tags after a page has accumulated enough Likes and Shares. That prevents a really popular page from switching it's tags to something very different than what was originally Like'd, which could be obviously used for 'bad' things.
I hope that helps explain, but if you need anything else, just let us know.
Thanks,
Alex
