> Well, Photoshop is *way* too expensive for my blood... I like to use Paint

Well I found a copy of 3.51 on Usenet for $100 a couple years ago and I intend
to keep using it as long as possible since 4.0's UI got a bit harder to use.
It's just one of the most intuitive, well-coded (actual efficient code, not
bloatware; imagine that for a modern Windows app!) apps I've ever seen. Since
it's multithreaded, it will also take advantage of multiple processors if you
have them.

Well grayscale is usually 8-bit, thus what you call "256 color B&W" is really
grayscale. Strictly speaking, B&W means just black and just white, no

This is what I was talking about, in Photoshop terms.

That is why I said "B&W images" rather than "grayscale images". And further
down the email there was an URL at which you can see some of my cleaned-up
scans that compressed rather well.

Hmmm, 3.51's is decent and offers multiple compression levels.

It can export transparent gifs. However I've noticed sometimes wierd things
happen with the colors, like black and white get reversed, and I'm not sure if
it's Photoshop's bug, something wrong with the standard or a browser bug.
Anyhow for non-transparent gifs I've never had any problems.
