Google A few months ago, Google open sourced the VP8 video codec as part of the WebM video project, to create a truly Free/free unencumbered video format for the web as an answer to the non-Free/free patent-encumbered H264 format. Today, Google launched a new image format for the web, WebP, which aims to significantly reduce the file size of photos and images on the web.

Possibly quite correct. The DCT is a pretty damn good image transform. The problem with it is computational cost and the ijg libraries frankly suck.

For something like WebP to get any traction is if it's even simpler and easier to implement and computationally more efficient. Right now the google pages about webp seem to be out of commission so I can't look into this part myself.

jpeg2k is a pretty horrific over engineered difficult spec to code and it's computationally even more expensive than jpeg. Quality wise jp2 isn't clearly better than jpeg, just different with tradeoffs in what artifacts you get.
