GmapsMania

This plugin allows you to directly embed Gmaps code in your posts or pages using the [gmap] shortcode.

HOW TO USE IT: When you are in the Write Post or Write Page screen, find the « Custom Fields » area. If isn’t already there, add a custom field named exactly « gmap » (without quotes) and copy and paste in the value field the whole code you obtained from Google Maps. Write anywhere in your post or page the « shortcode » [gmap]: when displayed on the blog it will be repalced with your Google Map. Save and publish. You are done!
