title: Add upload feature to Magento CMS
body: <p>I’d like to add a custom field to my CMS pages which allows someone using the admin panel to upload and specify an image of their choice to appear as a banner on the page.  I would set where this image appears in the template.  Has anyone come across this functionality or have any recommendations on where to begin?  </p>
  
  <p>I am running 1.3.x and I have read that 1.4 has nicer tinyMCE features, so I imagine this will be easier with an upgrade, is that true?  Anyone have any experience with richer CMS like this for Magento?  I am hoping to find a solution similar to the way Custom Fields and Write Panels work in Wordpress.</p>
