ZeeMaps

With a few simple clicks, you can post a customized, interactive Google Map in your 
blog. Follow these simple steps to post your map:
<ul>
<li>Go to the ZeeMaps server (http://www.zeemaps.com) and create your map</li>
<li>Add markers, regions to your map</li>
<li>Add one marker at-a-time, using Additions->Add Marker menu item, or use Additions->Upload CSV to add multiple markers from a CSV file or Google Spreadsheet</li>
<li>After your map is done, note the map number for your map (the number on the map URL after the parameter group=)</li>
<li>Make sure you have the ZeeMaps plugin downloaded and activated</li>
<li>Go to edit your blog entry</li>
<li>In the second row for your blog editor menu buttons, you should see a new button with the Google marker icon</li>
<li>Place your cursor in the location where you want to publish your map in the editor window</li>
<li>Click on the Google marker icon button</li>
<li>Enter your map number and customize your published map in the resulting dialog</li>
<li>Click on the insert button</li>
</ul>
This should add some text to your blog like:
[zeemaps 45 w=100% h=500 add geosearch]
This text will be replaced by the map in your blog.

Create and customize an interactive Google Map using ZeeMaps and then easily publish it in your blog post.
