In the past few weeks, I've been experiencing some issues when sharing my blog-posts on Facebook:
First, when I post the link to Facebook and have to chose the thumbnail I'd like to show, I can only chose few pictures available in the post rather than all of them. In other words, some pictures are part of the thumbnail choice while some others aren't.
Second, once I've posted the link and someone wants to share it from my profile or my page no thumbnails appear! This is extremely annoying because it refrains many people from sharing.
How can I solve those two issues?
The blog I need help with is thejrexpress.com.
