I just released my first WordPress plugin – the WP Gallery Image Shortcode plugin. This plugin lets you add an image to a post or page from the WordPress gallery on your site using a shortcode. Normally when you add an image, it embeds an image tag and sometimes an anchor tag that each includes your site URL. This might be fine for some sites, but if you ever need to move or copy content from one URL to another, these yet more places that you must modify to get that content working in the location.
I finally got tired of it and wrote this plugin. It allows you to use a shortcode in your posts and pages that refer to uploaded images by ID, name, or title. The easiest is probably by title since that is what is displayed in the admin panel.
The plugin is being hosted by the WordPress plugin repository. Check it out and let me know what you think.
