codinghorror.com — It's surprising that the venerable JPEG image compression standard, which dates back to 1986, is still the best we can do for photographic image compression. There's a sequel of sorts to JPEG known as JPEG 2000. It's the logical heir to the JPEG throne. The promise of JPEG 2000 is higher image quality in much smaller file sizes.

It can be licensed for free for commercial, closed-source projects, but the reference implementation of Microsofts 'HD Photo'-standard has a license which explicitly states that it can not be used in open-source projects. (See the license section from: <a class="user" href="http://en.wikipedia.org/wiki/HD_Photo)">http://en.wikipedia.org/wiki/HD_Photo)</a>

why is it suprising that we still use a standard from 1986? The majority of the algorithms used in modern computing were invented in the 1950's, before computers even existed. It's not a question of having an algorithm that's high tech and modern.....these are simple math algorithms which have already been optimized. If it's not broke, don't fix it.

I meant multiple pages, not layers -- like TIFF

This is just a plant by M$. They are trying to get rid of JPEG. Old news!

One of the best features of PNG is alpha transparency support. this is especially handy for web designers. Alpha transparency is now supported in IE (as of version 7.0) and we can expect to see designers make a lot more use of it.
