Another reason user module needs to be rewritten... or maybe this is just a file handling issue

I'm blaming user module even though I know intimately that I shouldn't: a 2 hour estimate to add user picture upload to the client's custom registration form has become a journey through HTML form and PHP file handling hell because even Drupal core doesn't let you upload a user picture when uploading. Finally just put it on the second page of the client's two screen login process.

Wrote a module almost just like http://drupal.org/project/reg_with_pic

I hope that people who need that module find the Register With Picture upload module through this page, because trust me, I looked for it before writing my own. If it doesn't quite do what you need though, contact Agaric for our version– because it does do things slightly differently, in ways that the client happened to need.

This was just a complaint, technical documentation here:
