title: How can you tell png8 from a png24
body: <p>I'm working on a website that uses lots of png24 files, for transparency.</p>
  
  <p>I need to replace them with png8 files, as all the png fix style javascript workarounds for png24 cause IE6 to lock up randomly. </p>
  
  <p>See this link to get an idea of the symptoms IE6 displays - <a href="http://blogs.cozi.com/tech/2008/03/transparent-pngs-can-deadlock-ie6.html" rel="noreferrer">http://blogs.cozi.com/tech/2008/03/transparent-pngs-can-deadlock-ie6.html</a></p>
  
  <p>Does anybody know an easy way of targeting existing png24 files, to replace them with the png8s?</p>
  
  <p>I'm using a OS X, and file browsers like Adobe bridge don't show this, nor can I find the info on the commandline, or the finder.</p>
  
  <p>Help!</p>
