Basically i want to pass an Image url from a post to the open graph image meta tag so i can choose which image to show on a facebook post.



I found this solution, but it only work if your fist image is what you want be shown, it didn't give you control.



<b:if cond='data:blog.postImageThumbnailUrl'>
<meta expr:content='data:blog.postImageUrl' property='og:image'/>
<b:else/>
<meta content='[The image url]' property='og:image'/>
</b:if>


Thank you
