Wrong photo on link to joomla site publicated on facebook


I have a Joomla site (Joomla 1.5) which has some articles.
I have published a link on a facebook group. This link points to an article which has some photos.
Facebook then shows a photo automatically, but the photo that appears is related to a very old article, not to this one.
Is it possible to change the photo on facebook, or "explain to facebook" that this photo is not related to this article/link?

Thank you.

You'll need to set Facebook Open Graph tags on the page so that you can tell Facebook what information such as photos and descriptions to use.

This part is for the image but it is a good idea to set the description and other information

<meta property="og:image"
content="location-of-image.jpg" />

Open in new window

Go to this link for more information: https://developers.facebook.com/docs/sharing/best-practices#tags

og:image – This is an image associated with your media. We suggest that you use an image of at least 1200x630 pixels.

Use this link to test the page https://developers.facebook.com/tools/debug before you post it on Facebook.

Thanks for your answer.

I tryied but it seems is not working.

This is the link I tryied:

If you look at the source code you will see this:
<meta property="og:title" content="Club Escacs Valls" />
<meta property="og:type" content="website" />
<meta property="og:url" content="http://www.escacsvalls.com" />
<meta property="og:image" content="http://escacsvalls.com/templates/ja_purity/images/logo.jpg" />
<meta property="og:site_name" content="Club Escacs Valls" />
<meta property="fb:admins" content="1013909369" />

But it looks like nothing has changed. Maybe facebook has some kind of caché ?

Hey mate,

In the last line of my original response I said this: Use this link to test the page https://developers.facebook.com/tools/debug before you post it on Facebook.

See if that helps :)
