Wrong Photos displaying from copy & pasted links

Hello, I just launched my site a few days ago and I’m having some issues. One of the main ones is when I copy and paste one of my posts into G+ or Facebook the wrong image will display.

For example, if you view this recipe post https://tinseltownmom.com/bethenny-frankels-skinny-fried-chicken/ and try to paste it elsewhere a completely different image will display. I have to delete the wrong image and manually select the correct image from my desktop.

Also, when I try to pin a blog post, it takes me to a page that has images, not the custom Pinterest and Pin it box. Please help!

My website is https://www.tinseltownmom.com

Thanks you
