[jQuery] jQuery uploading. Data type question.

[jQuery] jQuery uploading. Data type question.

<div dir="ltr">Greetings!
I am trying to use the Ajax File Upload here: <a href="http://www.phpletter.com/Our-Projects/AjaxFileUpload/">http://www.phpletter.com/Our-Projects/AjaxFileUpload/</a>
Anyway, I think it's already good enough but whenever I try uploading a file, it doesn't recognize the filetype. Kind of like a corrupt file.
Base on the jQuery docs, the DATA TYPES I could find were "html", "json", "xml".
What data type do I need to specify if I'm transfering a whole file and storing it in a BLOB in MySql?
Thanks a lot. Hope you guys know about this.
