[Tuglist] Fwd: Re: [l2h] png images

[Srinivasan Ramakrishnan]

Here are a few things I have come across when dealing with PNGs and JPEGS

# PNG has support for transparent portions in an image, which JPEG doesn't
although GIF does
# Another point is GIF89a supports animations, which PNG doesn't.

A few interesting resources on the web:

PNG Vs JPEG
http://www.im.lcs.mit.edu/bh/image-types.html
(I couldn't connect to this resource, so I used Google's cache)

JPEG FAQ
http://www.cis.ohio-state.edu/hypertext/faq/usenet/jpeg-faq/top.html

History of PNG
http://www.libpng.org/pub/png/pnghist.html

JPEG/GIF/PNG comparative study
http://tlc.nlm.nih.gov/resources/tutorials/demos/compression/graphics/jpeg-g
if-png.html

And, definitely a *must* read
