jqUploader
ActionScript, Flash, Javascript June 20th, 2007

jqUploader is a jquery plugin that substitutes html file input fields with a flash-based file upload widget, allowing to display a progressbar and percentage.
The plugin uses the form action attribute value (normally pointing to a server side script handling the upload and other data manipulations, and appends a variable “jqUploader=1″ so that the upload code is initiated when it sees that key/value is on the posted data.
