I'm currently using the following custom Stylish style sheet in
Firefox 2.0.0.11...
*{ color: black !important ; background: none !important; background-
color: white !important }
a:link { color: gray !important }
a:visited { color: purple !important }
a:hover, a:active { color: red !important }
img {display: none !important;}
When combined with proxomitron ad blocking, it does a pretty good job
of rendering web pages in black and white with no images.
The only problem is forms with an input tag with type=image. These
images are not blocked.
There are test cases at the bottom of this page...

Is there any way to block these through css? Ideally, I want to show
the alt text in place of the image but simply blocking the image would
be an improvement.
You can get the Stylish plugin here...
