This plugin serves a very specific function, namely turning any element with an ID on your current webpage into a upload tool that accommodates both single and multiple files. This solution came to be because the programmer had to find a solution for upload difficulties he had to face when working on a CMS.
From a technical standpoint Uploadify employs Flash and a backend upload script that you can choose at will in order to handle files. The programmer explains that the main asset of this service is the way that JavaScript and Flash are interconnected, and that is why the upload and transfer of data are taken care of so efficiently.
The developers are Ronnie Garcia and Travis Nickels. They can be contacted easily through the site, and you can send them not only your insight but also make a donation should you find this plugin useful. Consider doing so if Uploadify lessens your workload and lets you focus your attention on other tasks at hand.
