Thanks for that indyrank.
Q: Can I show different content in the preview?
A: No. You must show Googlebot and the Google Web Preview the same content that users from that region would see (see our Help Center article on cloaking).
The article is undated, but seems to have been published very recently (post launch).
Q: I want to block my images from being indexed, but Iím happy with them appearing on a preview image; how can I juggle the two?
A: In order for images to be embedded in previews, it is important that they are not disallowed by your robots.txt file. In order to block crawlable images from being indexed, you can use the "noindex" x-robots-tag HTTP header element.
They forgot to say how this can be done in .htaccess:
<Files ~ "\.(gif|jp[eg]|png)$">
Header append x-robots-tag "noindex"
Hope this helps.
