There is no data other than the image. But dragging the PNG into Creator does indeed give you the creature as structured data. Renaming the PNG doesn't affect the data transfer, but any sort of editing of the image does. They're using steganography, hiding one message inside another. In this case, they seem to be using the least significant bits in all the pixels. fjordaan Thu, 26 Jun 2008 09:25:00 GMT http://hotwired.lycos.com/webmonkey/html/97/12/index2a.html fjordaan Thu, 21 Feb 2002 19:01:36 GMT http://www.libpng.org/pub/png/pngapbr.html fjordaan Mon, 20 Nov 2000 00:11:15 GMT http://www.w3.org/TR/2003/PR-PNG-20030520/ fjordaan Sun, 01 Jun 2003 17:46:06 GMT http://psydk.org/PngOptimizer.php fjordaan Sat, 13 May 2006 15:01:45 GMT http://www.satzansatz.de/cssd/tmp/alphatransparency.html AlphaImageLoader filter flaws in IE6 fjordaan Tue, 27 Nov 2007 10:53:50 GMT
