Digital Photography Tips, Tutorials and Resources
Do you want to fix the Facebook thumbnail image for your blog post? Sometimes Facebook displays the wrong thumbnail image for your article. In this article, we will share how to fix the Facebook thumbnail issue in WordPress.
Why Facebook Shows the Wrong Thumbnail Image
Many of our readers asked about why Facebook commonly picks the wrong image for their post when they try to share it.
There are several reasons why Facebook picks the wrong thumbnail for your post. Facebook works with Open Graph (og) tags to know which image to pick, so one reason is that multiple images are set for the og:image tag.
Other possible issues include caching plugins, CDN conflicts, missing og meta tag for the thumbnail image, and more.
You may be confused about where to start in order to fix this problem, however there are few simple things you can do to make sure Facebook picks the correct thumbnail for your post.
Lets have a look…
Adding a Thumbnail Image Manually
Sometimes this is the quickest and easiest solution, although it doesn’t work in all cases and it isn’t the most reliable.
If you share any post on your Facebook page and it misses the thumbnail, then simply click on the Add Image (+) box to upload the image of your choice, and select it as the thumbnail of your post.
The problem with this method is that it will still miss the thumbnail, or show the incorrect one, when other people share your post on Facebook.

Telling Facebook to Use Your Thumbnail Image
Some WordPress SEO plugins, including WordPress SEO by Yoast, allow you to designate a specific thumbnail image for your post.
If you are using Yoast SEO, then simply scroll down on the post edit screen and click on the Social icon (it looks like three connected dots). You can upload your Facebook post thumbnail here and it will show you a preview.
Now, your post will tell Facebook which image you want to display for the thumbnail.
However, sometimes Facebook will continue to show the wrong image even after you’ve done this. That’s because they have cached an old copy of your blog post. Find out how to fix this issue in the next step…
