Lazy and Progressive: Image loading and perceived performance

Like teenagers, web pages go through some jarring transitions as they develop. This talk is about that awkward time *after* a page’s content and/or layout has loaded, but *before* the images come in.

What can we do to make this time shorter, or, at least *feel* shorter? How can we use it to set user’s expectations, and minimize nasty surprises? And why, sometimes, should we try to intentionally make this time as *long as possible*, so that images arrive *just in time* rather than *as soon as possible*?

In this talk, we’ll discuss the code-y hows and UX-y whys of lazy and progressive image loading on the web.
