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://www.lifehacker.com/software/privacy/geek-to-live--hide-data-in-files-with-easy-steganography-tools-230915.php The digital equivalent of invisible ink is steganography software, apps that embed files and data inside other files, hidden from everyone who doesn't know any better.
