Hi

We've got a cutsomer, who want's to add a Facebook "Like"-button to their newsitems, so that when you open a newsitem, you can choose to "like" it on facebook. 

When facebook makes a preview of the page on the users wall, it uses the metatags "Title" and "Description" which is fine, because you can control these for each newsitem. However, facebook also grabs an image from the site, and to control which image is used, you need to have a in the page header. 

Is there any way to control this? I've tried changing the value with javascript, but it doesn't work with the facebook robot. 

Maybe I'm missing something obvious, but I would appreciate some input on this.

Thanks.

Hi Gorm, old chap!

You can use a NewsItemDetailsTemplateExtender :

Article on template extenders:

In the ExtendTemplate method do like this with the image url:
PageView.Current.Meta.Add("custom", "link rel=""image_src"" src=""[src to image]"" ")

You can find the image source in the extenders newsitem:
MyBase.Item.NewsImage

I think I need to do something like this - but I really don't understand it. What to write in my og:image property in order to get the news-image shown on facebook, when a news-item is liked?

I'm using the xfbml method, and has finally got title and description working - but I need a way to get the news picture shown, if it's possible.

Can anybody "translate" the text above with templateExtender and MyBase.Item.NewsImage etc, so that a "not-developer" can understand it, please?
