You can create an 'Upload' section on a site byt the following way.

HTML Code:
<input type="file" name="file" />
Make sure that you have a form

HTML Code:
<form method="post" action="thePage.extention">
other fields
<input type="file" name="file" />
some more field and radio buttons perhaps here.
finally a submit button.
</form>
in the action thePage must contain a script to upload things to your server. It all depend to the language that you will be using, ASP.NET, PHP, Perl, etc.
