Using your photo editing software of choice, reduce the number of dots per inch (dpi) until the image starts to look grainy. When the image starts to go grainy then this is the optimum point and you should no longer reduce the dpi.

I think Macromedia Fireworks has the option to publish an image for the web automatically and I think you can download a 30 day trial version (fully functional) from http://www.adobe.com/products/fireworks/

Save it as a "JPEG" image, make a backup copy, then try to save copies of the image decrementing the quality of JPEG compression untill the loss of information is visible. Then save your previous copy of the picture as the one you'll use on your web-site.
