Method 1: Uploading Images Manually

Let’s take a case where you have shared a content on Facebook with the relevant image. Now, Facebook has refused to upload the thumbnail that you have categorically arranged for sharing purposes. What is that you would do in such a case? You will see a tag saying upload the image. Use that tag and manually upload the open graph image you have sorted out for this purpose.

The image you upload in this case will stay in the photos page of your Facebook. You can always delete it from there without worrying about the thumbnail. The thumbnail image will remain irrespective of the fact whether or not you have in the photos page.
