Website images

[Alvo von Cossel I]

hi,

this may sound like the wrong discussion group to use but i assume that some
of you use HTML/ASP.NET in your websites and will know an answer.

with an internet connection, anyone can view a website, right? even on a Mc
or a Linux machine. so what is the best image fornmat? BMP is not the best
because it is a windows file format, WMF and EMF also.

does PNG work or is it also a windows file format?

which is better, GIF or JPEG?

GIF and JPEG are definitely the most widely recognized by all browsers. PNG
is usually OK. I think that BMP is not only too large having no compression
but, as you say, a proprietary format so I steer clear of them.

IMO, even though JPEG is good. nothing beats a GIF with a well optimised
palette.

BMP:
* full color
* no compression (so large files)
* windows only

GIF:
* 256 colors per image (out of full-color palette)
* good, loss-less compression (once image is reduced to 256 colors max)
* single color can be marked as "fully transparent"

JPEG:
* full color
* good but lossy compression (adjustable), good for photos
* no transparency

PNG:
* full color
* good compression
* alpha channel ("partially transparent" possible), BUT: IE doesn't support this
(I think IE only recognises 0% and 100% transparent)

Which is "better" depends on your needs.
