uploading

Following from this topic about using pictures as hyperlinks, I would like to set up a system where users can upload their demo sites through the front end I shall try to write with PHPR, doing the upload through the front, and this will make the demo site available to all users in school, so coming from this post about a front end for sites I want to be able to upload to a user created folder, filling in the details to the front end, user uploads, PHPR takes the user created thumbnail of the site, always called tn.jpg, and PHPR displays the thumbnail and details like in the cars database from templates, but clicking on the picture takes the user to a new browser window which opens to the demo site.

Closing the window returns the user to the database, so I reckon I can set up the tables and the basic structure of what I would like to do, but is it possible to do a bulk upload to a user's folder on the web server from the front end made with PHPR?
I know you are all thinking, yes I am an awkward git, but i am trying to learn this too.......
