Which do you think are better? Gif's or Jpeg's?
I like Gif's myself. 256 colors is max for any image i put on the web, anymore then that would mean horrific load times. And with error diffusion, the imagelook good and have good load times.
But i was also wondering, is, i hear stuff about png, i think thats it anyways, i was wondering, if theres anything good about that type.?

GIF and JPEG both have their advantages and disadvantages. Photographs look terrible as gif's for example, and anything with hard edges (text, for example) looks bad as a JPEG.
I'm not an expert on PNG or anything, but it seems to be a really good alternative to the other two. It's vector based, which means that it'll render hard edges really well. Maybe someone else could explain it better - I should do some reading up on it.
Are there any browsers that support it yet? NS 6 maybe? It's not really practical to use on the web yet because the common browsers don't support it...
P.S. Shouldn't this be in the Graphics & Design forum?

Both 4.0 and up browsers support PNG. I don't use it for photo type graphics as it is quite large. Looks good to replace GIF thou.

I like GIF. Good load times and it doesn't look as bad as Jpeg

It is sposed to have 256 different transparences, so that means partial transparence, but this is currently no fully surported by all browers

GIFs are better in most cases, with the exception of photographs, where JPEG's are best.

From my experience use GIF when your file size is 30k and below.
JPEG would be more suitable with 40k and above file size.
Hope this helps

I use GIF images for all my web graphics except for photographs which I keep in JPG format for better picture quality. I'm gonna go look into PNG though...

Justin, Wouldn't you want to use .bmp for photgraphs, that doesnt take away any quality does it?
But everytime you open up a JPG and save it it looses some of the quality. I read that somewhere.

Use JPEG for "natural" pictures (photos, etc.)
Use PNG for the rest (logos, buttons...).
I stopped using GIFs two years ago and never got complaints.
All major browsers support PNG.
Why (not) use PNG and not GIF?
+ PNGs are smaller
+ PNGs can be hi/true-color
+ PNGs are not based on the LZW-algorithm (which is still patented by Unisys!!!)
- PNGs can't be animated
The last one is a big drawback, especially for banners,
but since I don't own a licensed Grafix-Application I have no choice.

Who/What Invented PNG?
How do you go about inventing a image format anyways?
What are the other formats that can be used on the web?

Don't use bmp in a web site. The file size is scary! I always use jpg for photos. Loss of quality can be controlled by most graphics software (e.g. PhotoShop). It depends on the picture, but you can very often reduce file size without losing any quality. I got that one from my dad and he should know - he's in the printing industry and they use PhotoShop all the time.

Just wondering if the patent for GIF will be free for programmer. PNG to me is good, but not very popular, but it will.
