images not showing in posts

Hi, I am getting acquainted with the Presentation theme and am having the following problem. When I go to Appearance Customize and test the Home screen from there, and I click on any of the blog template examples, the images in all three of the examples appear on the post ok. But, when I access the same Home screen and posts through the menu options (with the url to the home page), non of images show up in non of the 3 templates (these are the example templates and posts I´m talking about). Can figure out why. Can you help point me in the right direction? Thank u. My url is https://marioescudero.org
