> modern operating systems recognize both .jpg and .jpeg Modern operating systems have much more advanced methods to regocnize filetypes. From web developer's perspective, I really hope JNG would gain more support, since it solves the biggest problem of JPEG, the lack of transparency support (so called "alpha-channel"). http://en.wikipedia.org/wiki/JPEG_Network_Graphics http://en.wikipedia.org/wiki/JPEG_Network_Graphics 24-bit PNG is often really impractical as a replacement for JPEG due to its huge filesize (for certain type of images).
