Hello all I will be showing you how you can implement the Google Maps into your website.
1) You will firstly need to sign up for the API service which is provided by google.
You can click here to sign up http://code.google.com/apis/maps/signup.html
Once you have done this you can use an Example of this code below to create a page in which people would have access to Google Maps through your website.
