Hi I am new to Drupal and have installed the YUI editor module for the theme that I am currently developing. What I would like to do is have images that are uploaded by authenticated users from their local computers be no wider than a certain width. And if the users do upload an image larger than this specified size I would like the image scaled to fit this width constraint. Is this possible? I've looked everywhere and there doesn't seem to be an answer to this.

Any help is greatly appreciated, thanks.
