Images not appearing on website

I am editing by squarespace website with this layout. I save it as normal. 

However, when I test my website, the images are gone and formatting is weird. 

Does anyone know how to fix this? Link to websitePassword: 123

I think there could be errors in your code block that need to be resolved.

Can you try to remove the code block to see if you can get the formatting to stay the same as the backend of the site?
