Plupload – Making Multiple Uploading Easier than Ever

Plupload allows you to upload files using HTML5 Gears, Silverlight, Flash, BrowserPlus or normal forms, providing some unique features such as upload progress, image resizing and chunked uploads.

Plupload is currently separated into a Core API and a jQuery upload queue widget this enables you to either use it out of the box or write your own custom implementation. Drag/drop support of files is currently only available in Firefox 3.5+. Image resizing is only possible on Firefox 3.5+ and only at a fixed quality.

Requirements: jQuery Framework
