What do you want the map to be of ?
Is it a county, local town, specific street or estate ?
Do you want to start with an image and be able to zoom in ?
Which web editor are you using ?
On the vague offchance you have FrontPage 2002, click on Insert, click on Web Component, scroll down the list in the left panel to Expedia Components, click on it and select either of the two options to "Link to a map" or Static map". Follow the prompts. Job done.
Post with more information and one of us will advise further.
