title: What's a good, free, drop-in set of mimetype icons?
body: <p>I want a set of mimetype icons to go with my file uploads, to show in users' files lists and the like.</p>
  
  <p>It should be:</p>
  
  <ul>
  <li>16x16 PNG or JPG (other sizes through 64x64 would be a bonus but not required)</li>
  <li>already organized such that I can do e.g. mimetype.sub('/','-') + '.png' and get the icon file name (I'd like to avoid spending a bunch of time figuring out the associations)</li>
  <li>not platform specific, preferably using properitary apps' native icons where available (e.g. a .zip icon should not look like a KDE box)</li>
  <li>pretty but readable and suitable to a general audience ;-)</li>
  </ul>
  
  <p>What's a good package for this?</p>
