Hi Rich, u might try this Project. https://github.com/valums/file-uploader
Demo: http://valums.com/files/2010/file-uploader/demo.htm I have used it successfully in a few Tap5 projects and was not that hard to integrated. Sadly i haven't had the time to release it as a standalone tap module. It even supports HTML5 Drag&Drop and falls back to JS if not supported.
