The proportion of image data in the typical payload of a website can be significant. Lazy loading is a solution that lowers initial page payload and load time, without removing content. Non-critical resources are instead loaded at the moment that they are needed. Also, load MathJax async in head if required, rather than at end of body. Close #1106
