title: Make several PNGs into one ICO file
body: <p>With Windows ICO files, you can pack several different sized images into the same ICO file - Windows then picks different sizes based on what it needs. (<a href="http://msdn.microsoft.com/en-us/library/aa511280.aspx#size">see here</a> for info about icon sizes)</p>
  
  <p>There are lots of free online tools that take a singe image and make it into an ICO file, but are there any free online tools that take <em>several</em> images and make them into one ICO file?</p>
