You mentioned just one particular upload implementation which you don't have to use, of course.
Another option is using HTML form with method "post" and the input control with
type="file"
.
Also, there is a number of jQuery solutions available. I like this one:

^].
It allows to dynamically add files one by one in a convenient way.
You can find some more if you need to:
