Colors: 256 vs High Color

Apologies if this is a FAQ question....

I've noticed that many graphics, especially ones with large areas of
graduating colors, when viewed in a web browser w/a monitor set at
256color, look grainy. Sometimes the graininess is acceptable, sometimes
it's not. I know that saving as GIF's sometimes helps the problem, but then
again, sometimes it doesn't.
I also know about 'browser safe' palettes but haven't really followed
that...does that make a difference inthe graininess I'm seeing?
or is it fairly inherent with 256color and things like photos/non-solid
color images?
Advice?
Thanks!

Yes, it is.  Here are some FAQ sites to look at:

FWIW, the short answer is that web browsers are not optimized
as image viewers, and their shortcomings are pretty glaring
on 256-color displays.  Much of the art of web image design
lies in finding ways to work around the limitations of the
most popular browsers.

1. How to chang display from 256 colors to High Color or True Color

My application runs on a couple of NT 4 machines that are often in 246 color
mode. (It took me a while to figure out why it would sometimes display
correctly but not at other times. I would like my ap to detect this and
change the mode to high color or true color (if available) when it loads.
How do I do this.  Mostly my aps run on NT or W2K but I would like this to
work on 98 or 95.

Thanks
