OK Mr. Duh, you're squabbling over the wrong issue. Replacing the white with some background color is not what he wants to do, so just let it go... Besides, it takes a lot of work to redo all your pictures if you decide to change your background.

In answer to the question, it would probably be best to save your pictures in .gif format, which supports transparency. You said they are technical drawings, so I assume they are not color intensive (.gifs have a 256 color limit). I would recommend .png, except that as far as I've seen, the transparency doesn't work in Internet Explorer.

So, to convert:

Image > Mode > Indexed Color. There are a couple of options for choosing the color palette. You can play with those, but make sure Transparency is checked.

Image > Mode > Color Table. This shows the palette of colors you chose. Select the eyedropper, then click the color on the image itself that you want to be transparent (in this case, the white background). This will change everything that is that color in the image transparent, so be careful there is not white somewhere in the interior that you want to remain opaque.

File > Save As > technicaldrawing.gif

Or if you're really adventurous, you can try "File > Save for Web". There are more options for optimizing .gif files there.

As for DuhMike, I guess ignorance is not bliss, huh?

Change the white to the same color as your web page.

duh...

ok...been there, done that!

No you have not done that.

If you use a little square of color from the background of your drawings

and

use that little square of color as your background on your web page then there can be no difference in the colors.

DUH.
