Learn from images

[tcp]

It is unrealistic to expect us to get high quality images of all the different people we have involved in a course.

• [ ] Unlink Splash Page Carousel images from Teacher images in the CMS
• [ ] Have a section to add images to the splash/home carousel separate from adding teachers.
• [ ] Make the Teacher Images Avatars
• [ ] Redesign the "Who You'll Learn From" section to be avatar focused on the Course Overview page
• [ ] Make the "Who You'll Learn From" section a carousel as there's actually a lot of people per course not just 3-6
