## 説明

Smart Image Loader loads images which are visible in the initial viewport of your
website before any images whose position is “below the fold”, outside the current
viewport. Those images can be loaded as soon as the visible images are finished 
loading or “lazy loaded” when they would become visible. This can be useful for 
bandwidth saving on mobile devices.

**There is no need to insert any additional code into your website, just install
the plug-in.**

The default settings are fine in most cases, but you may want to adjust them for
optimization.

Smart Image Loader is tested and works down to Internet Explorer 7, disabled below.

Note: there is currently no support for (CSS) background images.
