They make a great program called stegawatch. Ask for Robin, she's very helpful.

Eyemage IIE is a brand new piece of free software that allows you to encrypt with awesome security any file or text into a bitmap image. You can hide photos in photos, zip files in images and Word documents in diagrams then send those images to your chums who can decrypt them. Alternatively you can just keep them safe on your hard drive.

Try it; it's free and fun to play with. (Look in 'Windows Software'; plus you need IE to get to the page.)
