Having trouble with images and blue boxes showing up

I am totally lost here! I am trying to set up an ecommerce site using woocommerce but loading the images is not going very well. When I go to the website and click on the shop page- I see a bunch of blue boxes with two squares in them. If I click on the blue box then my image comes up.

I know nothing anymore about coding- haven’t done that in many years. I chose to work with wordpress because I supposedly didn’t need to know anything about coding.

So my question is how do I get rid of those boxes and have the images only or is there an easier ecommerce plugin or whatever it is called that I can work with.

The website is tchomedecor.biz

Thank you to anyone that can help!
