As promised, here is a quick guide to .png and .jpeg2000 (both taken from Wikipedia)
.png = Portable Network Graphics (PNG) is a bitmapped image format that employs lossless data compression. PNG was created to improve upon and replace the GIF format, as an image-file format not requiring a patent license. PNG supports palette-based (palettes of 24-bit RGB colors), greyscale or RGB images. (http://en.wikipedia.org/wiki/Portable_Network_Graphics)
JPEG 2000 = JPEG 2000 is a wavelet-based image compression standard. Created in 2000. JPEG 2000 requires far greater decompression time than JPEG and allows more sophisticated progressive downloads, yet averages similar compression rates. JPEG 2000 becomes increasingly blurred with higher compression ratios rather than generating JPEG's "blocking and ringing" artifacts, complicating direct comparison of their respective compression rates.

So, now you know!
