Use URL short codes in WordPress page/post
URL ShortCodes plugin adds support for a basic short codes to use in your post/page editor that produce correct absolute URLs.
Sometimes you want to put the base URL (that of the blog, or that of the active template) in your content editor. Times when the template customizing isn’t quite flexible enough. With this plugin you can use [url_base] to output the base URL of the blog (as set in your Settings). Or, you can use [url_template] to output the URL of the active template.
<img src="[url_base]/test.png /> in your editor might output
<img src="http://localhost/wordpress/test.png" /> (if http://localhost/wordpress is what you have configured as your blog URL in Settings).
The supported short codes are as follows: * [url_base] – the configured blog URL (set in Settings). E.g. http://localhost/wordpress * [url_template] – the URL of the active template. E.g. http://localhost/wordpress/wp-content/themes/mytheme1
