How to Install 1. Unzip the zip file somewhere. This gives you a folder called barcode_posters_widget. 2. Upload that folder using FTP to the wp-content/plugins folder on your web server. 3. Go to your Plugins -> Installed screen in the WordPress administration and Activate the Barcode Posters plugin. 4. Go to the Appearance -> Widgets screen and drag the Barcode Posters widget into your sidebar. If you're using a caching plugin such as WP-Cache you may have to delete your cache before the new sidebar widget appears.
