In the left menu, click the "+Content" tab. Select "Features" and then scroll down the next column to the right until you see the images with 2 photos side-by-side. Note: You can choose another block if you like.
The content block with the 2 images will be added to the webpage.
Now delete the elements that you don't need. If you want to show only the 2 images, then click the sub-headings under each image. When the tool bar appears, click the right arrow in the tool bar to expand it. Then click the "trash" icon to delete the element. Repeat with the other sub-heading and also the text boxes if you do not need them.
If you choose not to use the buttons, click on the button you wish to delete. Then click the 3 dots in the lower left of the screen. Click "Remove This link". In the next box, click "Continue".
To add your images, click on each image box and add the photos from the next box.
