Sorry, I'm just seeing I was assigned to this!

The images look good to me @XAJX179! But I'd also like to get @JoshDevHub's blessing on this before merging since he's reviewed the meat of the changes in the other PR, and can judge this much better than me.

These look good!

Just one request: since we moved the new content you're adding to its own lesson, can you change the dir name that these images will exist in?
