Hello there, I would like to know if there is a way to create a Static/Default thumbnail for when my site is shared on Facebook. Usually it automatically loads a blurb from whatever page is being shared, and what appears to be a random selection of photos. I want ALL pages to load only one image, and not give a choice of Thumbnail.
I have tried a few Plugins that say they do this, but none of them work/are old and outdated. I searched the Forums and couldn't find anything on this topic since May 2013. I know Facebook changes their algorithms all the time so was hoping there is a fix by now.
Any ideas? The site is http://www.bcreptileclub.ca
I am using Twenty Fourteen and a Child theme of it.
