Can you post a URL so we can be sure what's going on?
What can happen is, if you edit the page itself without opening it as part
of a web, FrontPage will create a reference to the image using the file:\\
reference. Basically this points the image file to your hard drive. Since
you're on your computer you would be able to view it fine since your browser
can find the file on your computer. When viewed on another computer it won't
show an image since the computer doesn't have the particular file on it's
hard drive. To get around this, make sure that you are first opening a
frontpage web that has the web page and images in it. Then FP will figure
out the correct way to link to the images.
Hope this helps,
