[Plugin: Theme My Login] Adding file upload to the registration

Hi Jeff.
First, I’d like to thank you for this amazing plugin you made for us.
I’ve been working with it for a while now, and it’s a great help.
I was wondering, would it be possible to add a file upload to the registration and perhaps also the profile page? And if so, could you maybe at least point me the right direction on how to do this?
Thanks!
