Darron Devlin recently published two useful new PowerToys for OneNote 2003 with SP1:

OneNote Image Writer
This PowerToy is a virtual printer that enables the import of document images into Microsoft Office OneNote® 2003 sections. Any program that is capable of printing can send a document to the OneNote Image Writer just as it would when printing to a physical device. The printed document is converted into a document image that can be used as a foreground or background image on a OneNote page.

WebPageToOneNote
This PowerToys adds a WebPageToOneNote button to the Standard Buttons toolbar in Microsoft Internet Explorer 6 or later. Click this button to copy an image of the entire current web page (WYSIWYG) to a new page in OneNote. The new page is created in a WebImageCaptures section in your notebook.

Grab the new powertoys to install and use at Darron's web site. As mentioned in the past, you can also download a couple of useful add-on powertoys for OneNote from Microsoft.
