Hmm, a question here, the Huffman compression technique that is used in many of
the newer compression algorithms(RAR, ARJ and so on) is used in the zip format
as well, If I'm not misunderstanding what I read. But, as far as I know, the PNG
uses a dynamic compression table, in difference to the standard zip algorithm
that uses a static table. am I correct or totally lost in my compression?

Another file format I'd like some tips on is the FIF(Fractal Image Format) 
I had a compressor/viewer for this once, but lost it as so many otehr progs.
Anyone has anything on where I can find a program that can store to this? It was
very good at shrinking files, admittedly with loss, but the technique used made
it possible to zoom into the image in a totally different way than any
rasterized(bitmapped) format allows.

 Take a look in announce.frequently-asked-questions for a list of
links that will take you to faq's on image file format formats and
related image resources on the net. It's the best starting place I
know to send you for the info you seek.

I've been looking into this issue this week.
PNG and JPG are complementary, not competitors.
Use PNG for lossless work-in-progress and still get some compression.  
Use JPEG for final pieces.

Yes, it just depends on the raytracer doesn't it?  :)

MIRO is pretty good though.

There was a great one on Iterated System's website (www.iterated.com), but I
can't seem to find it (the site's so damn big!!!).  It was very fast and
efficient... shame I can't find the installation file any more... :)

  This is a FAQ, not a misunderstanding. I can add it to the VFAQ page
if you want.

Who thinks that JPEG works by reducing colors?  I've never come accross that
legend.  People either know the difference between JPEG and GIF, or they
have no clue how they work at all, in my experience.

There are quite a few people out there who think that JPEG-files will
always be smaller than GIF files. I think the faq should mention that.

A penny for your thoughts.
Mine are more expensive.

  I added a note about this.
