Using the File API added to the DOM in HTML5, it's now possible for web content to ask the user to select local files.
FileReader pairs very well with Drag n Drop to allow for drag 'n drop file uploads, and if neither of those features are present, the fallback of providing an
<input type=file> is rather easy.
Fully supported in Chrome, Firefox, Opera, Safari 6 and IE 10. Partially supported in Safari 5.1 (lacks FileReader support).
