PreloadJS

PreloadJS provides a way to load content only when it's needed.

The library is modular by design, was specifically created for larger assets, and comes with some nifty tools all developers will love.

By default content is loaded via XHR2, but the library also degrades to XHR and tag-based loading where this is not supported.

It also allows for loading queues, lazy loading, and various progress events for letting the developer detect when loading starts, is about to finish, or has finished (un)successfully.

PreloadJS also supports multiple queues at the same time, queue pausing and resuming, loading of data, not just asset files, and comes with a few examples to help developers get started on their own.
