.png ?

[jimmyhaha]

I have seen some website use .png for picture instead of .jpg or .gif.

what's png, and how's it compared to .jpg & gif ?

 

[Encryptic]

.PNG is a file format similar to .GIF, but it supports transparency among other things. The problem is that it's not universally supported like GIF and JPG are.

.png is much better , always use .png over .jpg or .gif when possible

its an open sorze thing

20 June 2003: The LZW patent expires today in the United States. However, patents on LZW are still in force in other countries. In mail dated Monday, 23 June 2003, Unisys attorney Mark Starr asserts that LZW patents are still in force in Canada, France, Italy, Germany, the United Kingdom, and Japan.

Please continue to refrain from using GIFs. More importantly, do not allow your communications to be censored by patent holders. Things you can do:

Oppose the expansion of software patents to your country, if such patents are not available there now.
Insist that standards bodies in which you participate make an an "innovation compatible" (IC) license a requirement for any patents needed to implement a standard.
Develop and support software that works with non-patented file formats and network protocols, instead of patent-encumbered ones.

png supports both pixels and vectors and alot of other stuff, also layers and you name it

As far as I know, PNG is true color which is better than GIF (256 color max) and lossless (which JPG isn't). It's a compromise between the two formats and the size is slightly larger than either one. But as FoBoT said it is open source. Compuserve can't decide to go after everyone that uses it.

pixels
vectors
true-color
indexed-color
alpha channels, even with true-color images (transparencies)
layers
interlacing
gamma correction
etc.

Slowly but surely, png will replace jpg & gif on the web.
