For every blog article or page that you are going to be sharing, it is important to actually set a social sharing image. If you do not specify a sharing image, the first image on the page will be used.
Specifying a sharing image can be done using the YOAST plugin on the individual page/post. In WordPress, navigate to the page/post you are going to share. Scroll down until you see the YOAST plugin and navigate to the Social tab.
Once there, you can upload a specific Facebook/LinkedIn image, as well as a separate Twitter sharing image.
