The World Wide Web Consortium (W3C) just released an update to the Portable Network Graphics (PNG) image format this week. The W3C introduced the initial specifications for this file format in 1996, with the group formalizing the 2003 standard in 2004.
The third edition of the PNG specification introduces three new features: support for High Dynamic Range (HDR) images, animation through Animated PNGs (APNGs), and Exif data storage.
