And sometimes Facebook get to pull a wrong image on my blog to represent the image thumbnail and at a point i thought maybe i forgot to add featured image on my post until i realize i was doing something wrong.
So Why is Facebook Not Picking up The Correct Thumbnail Image
The most common known reasons why Facebook pull a wrong thumbnail image when you share a link can be because of multiple images set in the open graph Image tags where your featured image is smaller than the other images.
Facebook uses open graph tags which is better known as OG tags to know which image is set to be used as a thumbnail image. If you do not know how to get through this settings, there are great plugins for this purpose
If you already have an OG tag set, other things that also causes this issue of wrong thumbnail image on Facebook is wordpress caching issue, CDN or some new plugin (s) you installed causing conflicts on your blog.

Upload Thumbnail Image Manually
But why upload thumbnail image on your wordpress blog when you can simply use a plugin? We have always recommend you to use lesser plugins on your wordpress site, this is why we write more on how to get things done on your wordpress blog manually rather than always using plugin.
One of the easiest ways to add thumbnail image is to manually upload them.

The ‘og:image’ property should be explicitly provided, even if a value can be inferred from other tags
The debug tool will show you whatever issues you are having with thumbnails and give you recommendations on how to fix them properly.
