Try using Adobe PhotoShop which is available in a cut down version
(PhotoShop LE) as a give-away with a number of products. This allows you to
define the resolution of the final picture. The full version is downloadable
from www.adobe.com, and a free try-out is available.

The best program I have used for making files smaller, especially for the
web, is FireWorks which is usually used in conjunction with the web
authoring tool Dreameaver.

Was your 30M file a JPG? I suspect it was a TIF which is uncompressed. Mono
images are often best saved in a GIF format if it is not essential to use
JPG.

Try altering the image size. Often the image is much bigger than necessary
and the file size diminishes by (roughly) square law as the image is made
smaller.

Good luck.
