Why no FELICS?

http://en.wikipedia.org/wiki/FELICS

If it's so much better than PNG, why there is no implementation? Looks like storage device manufacturers conspiracy.

Looks like storage device manufacturers conspiracy.
They probably acquired all patents needed to implement it.

It is left as an exercise for the reader.

If every reader does his own Lisp implementation, there will be no standard Lisp.

JPEG-LS is the emerging ISO standard for lossless/near-lossless compression of continuous-tone images. Marcelo Weinberger says about it:

JPEG-LS is being developed by ISO/IEC JTC1/SC29/WG1 (final committee draft document FCD14495-1 as of July 1997), and it is based on HP's LOCO-I algorithm.[3]

The main feature of JPEG-LS is its superior placement in the compression/complexity trade-off curve. Tested over a wide variety of image types, it was shown to be, on the average, within about 4% of the best available lossless image compression at a fraction of the complexity. In particular, JPEG-LS significantly outperforms FELICS and lossless JPEG Huffman at similar levels of complexity (it also outperforms lossless JPEG arithmetic, which is of significantly higher complexity). [...]

A software implementation of JPEG-LS, is now available at http://www.hpl.hp.com/loco/ There, the DCC'96 paper on LOCO-I is also available. The standard draft is also available through a link to the official JPEG Web site.

Is it better than FLICS and other alternatives?

I've never heard of FELICS before today. In which way is it better than PNG.

In English, we use the '?' symbol at the end of a sentence, replacing the '.' symbol, to indicate that it is intended to be interrogative.

What do you mean! I can ask questions anyway I want! Got a problem with that!

Are any of these codecs good for anything other than digital photos?

No, analog photos tend to be stuck on paper for which there is still no efficient (better than exponential) compression algorithm known to man.

Instead of trying to be clever you could try understanding the question.
