.PNG image files
 

Can all browsers view them?

Why would you want to view a PNG file in your browser?

Short answer - dunno...


Long answer...

PNG files ? Maximum bits: 24

The PNG, or "Portable Network Graphics," format was created as a successor to GIF. It features lossless compression for images with up to 24 bits of colour and most of the other features of GIF. In most cases it will provide at least slightly letter compression than GIF.

PNG files can be interlaced or non-interlaced. This won't affect how PNG images look in Graphic Workshop, but interlaced PNG files will cause Graphic Workshop to pause momentarily before its status bar begins to indicate that something's happening.

The PNG Compression control in Setup defines how hard Graphic Workshop will try to compress PNG files. It can range between one and nine. If it's set to one, PNG files written with Graphic Workshop will not be all that well compressed, but they'll write quickly. If it's set to nine, Graphic Workshop will usually manage to create smaller PNG files, but it will take a lot longer to do so. Intermediate settings will represent a tradeoff between these two extremes. Note that this setting will not affect the quality of an image stored in a PNG file ? it only deals with the compression effectiveness and the time it takes to write a PNG file.

....dunno :(

Just use good old GIF and keep the PNG files where they belong... in "Fireworks"

not just technically superior, but superior for its license. PNG came up after Unisys started trying to screw the world over GIF.

PNG works in most browsers out there, IE 5.0, Mozilla, Netscape 4. i think the problems come up with how well its supported in each. IE, of course, doesn't support them fully (i think in the alpha channel).

if all you're doing is looking to replace your GIFs with PNGs, you'll be fine. if you're looking to replace your JPGs with PNGs, .. i think that'd be inadvisable. and if you're looking to take advantage of PNG-specific features, test your sites in as many browsers as you can and maybe deliver content based on the Agent string.
