Add image in shared link on Facebook
When Facebook Facebook tries to share a link from my blog on Facebook, Facebook is able to pick up the text of the article, but it doesn't load the images to thumbnail.
Anyone would have any idea what I should do. The url is: www.sesmt.org

To make sure that Facebook will pick up the image you need to use the og: tags .
The basic tags you need to enter on your site:
<meta property="og:title" content="The Rock" />
<meta property="og:type" content="website" />
<meta property="og:url" content="http://www.imdb.com/title/tt0117500/" />
<meta property="og:image" content="http://ia.media-imdb.com/images/rock.jpg" />
It is interesting to use images in the ratio 1.91: 1. The optimal image size is 1200x630px, but any size above 600x315px following the aspect ratio is a good size.
It is worth taking a look at the Good sharing practices of Facebook or in this other question that I answered right here in Stackoverflow
I hope I helped.
When I tried to compare your website link, an image appeared. But if you do not like the image you, you can upload an image by clicking on "Add Photos/video", only with this you lose the thumbnail that Facebook puts, that is, it will stay the link and the image of your choice.
