I have an blog with related posts image in the top of it. I was waiting for something to fix it since they launch it, but didn't find anything yet so I'm asking for help with it.
The question is. When someone share an post with +1 button, it get the first image of the URL, which usually is one of the featured posts thumbnail.
In Facebook Share I got an plugin that get the 'featured image', but as far I researched, didn't find anyway to make it possible with G+.
So, one of the solutions I considered is making the "Featured post thumbnails" div 'hidden' to G+ button. Is it possible? Or make something similar?
You need to specify the +Snippet values. In the case where a post has no image make sure you keep the image definition but use the blog logo instead.
