How to Insert Yahoo! Maps in WordPress

1. Use UMapper. This free plug-in allows you to integrate Yahoo! Maps into your WordPress blog or website. It will only work if you have installed WordPress 2.8 or higher. As well as inserting maps, you can insert and move markers on a map to specify a location, create Geogames, such as darts, using the maps and is fully compatible with IE 7, Safari and Mozilla FireFox browsers. You can find the UMapper plugin at wordpress.org/extend/plugins/umapper/.
2. Download Yahoo! Shortcuts from wordpress.org/extend/plugins/yahoo-shortcuts/. Using the Yahoo! Shortcuts plugin, you can embed Yahoo! content into your blog or website, including maps. The plugin works by identifying keywords within your site content and highlighting them. When you hover your cursor over the highlighted word, it displays relevant Yahoo! content. By typing in locations, you will see a pop-up map when you hover your cursor over the text.

3. Install GeoPress from wordpress.org/extend/plugins/geopress/. This adds geographic tagging to your website or blog using photo websites like Flickr and a range of online map providers, one of which is Yahoo! Maps. Once you have installed the plugin, you simply type 'INSERT_MAP' into the text of your blog post after a location to display the relevant map to your readers. You can also choose the size of your maps and specify specific addresses or locations using the plug-in's star feature.
