Inserting photos on Code Pen portfolio project

I have an adobe portfolio site that I am using photos from on my Code Pen portfolio site project. I have the images coded as it is taught in the add images to our site exercise on the cat photo app but they are not showing. I’m getting an image such as this: cosmetic logo and I’m not sure why. All help is appreciated.

Can you share a link to your pen? It’s easier to offer help if we can see the code.
