Help! The image files aren't loading. Any idea why?

I started Unit 4 but the image files aren’t loading for lesson 3. I decided I’d just jump ahead to Unit 5 Lesson 1 (CSS) but most of the style examples are for images! How do I get the image files to load? Is this a bug? Even the images with the complete URL aren’t loading.

Having the same issue here. I would love to know if there is a solution. A key thing I noticed is that only the images from the hypothetical client scenarios load. I had chosen Kai and copied the image link for him and it does show up. Sadly, no other pictures load.
