BJ Lazy Load

By default, only images shown in the viewport are loaded.

If and when the user scrolls down, more images are loaded and displayed.

This technique saves bandwidth and improves page loading times.

This technique employed by BJ Lazy Load heavily uses a JavaScript trick, but for devices where JS has been turned off, the page will load normally nevertheless.

For responsive layouts and hiDPI-aware devices, BJ Lazy Load can also server size optimized images if needed.

Installation:

Unpack and upload it to the /wp-content/plugins/ directory.
Activate the plugin through the 'Plugins' menu in WordPress.
