Well that is interesting! I will say that it looks like the student may have discovered the Inspector Element in the browser and replaced the banner images at the local level. I say that because it looks like the missing image might have had an error in the url. If you put your eyes on it in class (or are you remote?), you can refresh and make sure the images are actually appearing? If these images are truly appearing on this student’s account, you can let https://support.code.org know and they can take a look.
Isn’t it great! I had her reset chrome and we all good!
Thanks for the speedy reply!
