Toolkits and Programming Libraries with PNG Support
I am looking for source of an H.261/H.263 codec and MPEG
The comp.compressoin FAQ answers this query.
http://www.faqs.org/faqs/compression-faq/part1/section-18.html
Tell me about Fast DCT (Discrete Cosine Transform) algorithms
The comp.compression FAQ attempts to do just that.
http://www.faqs.org/faqs/compression-faq/part1/section-19.html
PNG Source Code and Libraries
The source for libpng and zlib. Can’t do PNG without them.
Are there algorithms and standards for audio compression?
The comp.compression FAQ answers this question.
http://www.faqs.org/faqs/compression-faq/part1/section-20.html
PNG Documentation
Links to the PNG documentation in quite a few different formats.
PKunzip reports a CRC error!
The comp.compression FAQ tells you the sad news about this problem.

Where can I find Lenna and other images?
The comp.compression FAQ attempts to answer this for you.
http://www.faqs.org/faqs/compression-faq/part1/section-30.html
How about an Introduction to data compression?
The comp.compression provides the Cliff Notes version of the question.

PNG Support in Mozilla
Mostly history of how things have been going for support of PNG in the massive Mozilla project.
What is wavelet theory?
The comp.compression FAQ can tell you exactly what it is.

Lossless JPEG Codec
A freely redistributable lossless JPEG codec. Encoder, decoder, man pages, full C source, and some documentation.
Stuba mirror site
A mirror site for the big compression software site. See 0index.txt for a list of what’s here, an unbelievably large treasure trove.

PPM by Bill Teahan
This ftp site has a few PPM programs, along with Bill Teahan’s thesis.
FEI STU Bratislava,Slovakia,Europe
A very complete archive of compression programs, freeware, shareware, source, archviers, compressors, etc. They have it all. At last count this site has at least 1000 compression downloads
yabbawhap - Y and AP compression filters
Public domain code by Daniel Bernstein. (Note that this ftp site has an excellent selection of compressoin programs and code.)
Project Runeberg
A huge collection of Swedish language text files
Matsusaka University Anonymous FTP Server
An ftp site for compression software. This includes mirrors of some hard to find sites, such as those of D.J. Wheeler. Needs organization, and I often find it a bit slow from the US.
Bayes risk weighted vector quantization with posterior estimation for image compression and classification
by Keren O. Perlmutter, Sharon M. Perlmutter, Robert M. Gray, Richard A. Olshen, and Karen L. Oehler IEEE Transactions on Image Processing, February 1996). We investigate several VQ-based algorithms that seek to minimize both the distortion of compressed images and errors in classifying their pixel blocks.
Giflib 4.1
a copy of giflib
ftp://metalab.unc.edu/pub/Linux/libs/giflib/giflib-4.1.0.tar.gz
Hack Systems
Hack Systems makes DataSafe, a product that backs up files using Zip format.
Context-based, Adaptive, Lossless Image Coder (CALIC) (Huffman)
Xiaolin Wu’s static Huffman coding version of this program. Free of charge for research and non-commercial use. A total of 1.2 MBytes in a dozen or so files.
Datenkompression
A German language set of data compression links. A pretty good page of links, it probably doesn’t matter whether you speak German or not; the references mostly point to English language resources.

Wavelet Resources from Mathsoft
This page has references to a huge number of Wavelet-related research papers. I don’t know how many of them are online, but it is quite a treasure trove for the curious.
NeuQuant: Fast High-Quality Image QuantizationNeuQuant: Fast High-Quality Image Quantization
The NeuQuant Neural-Net image quantization algorithm (© Anthony Dekker 1994) is a replacement for the common Median Cut algorithm. It is described in the article Kohonen neural networks for optimal colour quantization in Volume 5, pp 351-367 of the journal Network: Computation in Neural Systems (Institute of Physics Publishing, 1994).
Zlib for the Palm Pilot
A test version of zlib ported to the 3Com Pilot
