Hi there. I’m new to WordPress. Working on my site that mainly will feature embeded vimeo movies to showcase our editorial work. Would like to be able to share a link on facebook that will pull in a thumbnail. I set featured image for a post, but it pulls up an image from my sidebar instead (or nothing at all). Tried looking around on the web and it point to code to input in the header or function files, but not seeing any changes when I do this. Is there someone that can help with this?
