missing exceptional-realty directory and associated images/videos

[jnoconor]

The video for this codealong references directories/files that are not included in this repository. The missing files are included in previous labs (for example: https://github.com/learn-co-students/CSS-Styling-v-000), so it's possible to copy them over and use them in this lab, but it's pretty confusing for students who in most other cases get everything they need for a lab when they clone the lab from GitHub.
