You can't create a file input with the filename pre-filled for obvious
security reasons, but you *can* still do some clever stuff here.  In
order to add a picture you'll probably need them to go through a file
dialog anyway to select the picture, and you can make this *actually*
be the file dialog of a hidden file input.  You can then move this
input around in the DOM without clearing its value, and submit it
transparently.

It's a bit hacky, but hey, web security is Serious Business.
