Great name by the way :)
I am sure Telerik will agree with me on this one but I would recommend using the radUpload control which is supplied with SiteFinity. For one you are guarenteed compatibility and two it is just a better and easier control to use and since you are paying for a system with those controls you might as well use them!
Telerik have loads of Samples and Demos
on their site and also there is plenty of Documentation
If you don't want to use it I am sure they will help.
