How can I specify which image to show in SERPs from my Rich Snippet?

[Techboy]

When I test my web page (which has Schema.org based content embedded within it) using the Google Rich Snippets Testing Tool, it displays the last image I have defined. I want it to show the first (primary) image.

Is there a way I can specify which image to use, or should I only be specifying one image?

Thanks.

Try using the following in the head section of the page:

This indicates, which image should represent the page.
It works with some - it doesn't with the other - you already use:

which is usually picked by Facebook and some other sites.

Give it a try and see if it works for you - I'm using both on my sites and it seem to be doing a good job.
