I made a new blog post on my website and provided an image for SocialGraph tag:
<meta property="og:image" content="http://i.imgur.com/someOldImage.jpg" />
The image was hosted on imgur, and posted it on the web.
After few minutes I decided to change the image and updated it to the new image that was also uploaded on the imgur. However as far as the html markup is concerned it does show social graph tag values according to the new image.
<meta property="og:image" content="http://i.imgur.com/someNewImage.jpg" />
But when I go to post on facebook the facebook preview shows the imgur error that
the image you request doesn’t exists or no longer available
Which means that FB is still trying to fetch the old image and not the new one even though I have updated it in the markup?
Why is this so, how can I refresh facebook social graph values for the url? Please explain its an important post and this way its like causing an embarrassment?
