| 17 | * This module relies heavily upon the Lazy Load plugin which was worked on by |
| 18 | * Mohammad Jangda (batmoo), the WordPress.com VIP team, the TechCrunch 2011 |
| 19 | * redesign team, and Jake Goldman of 10up LLC. |
| 20 | * |
| 21 | * The JavaScript has been updated to rely on InterSection observer instead of |
| 22 | * jQuery Sonar. Many thanks to Dean Hume (deanhume) and his example: |
