Brighten up your blog with a happy, happy flower!
Wildflowerizer is a plugin that lets you add a sidebar widget to your WordPress blog which randomly displays a photo that’s been recently added to the collaborative field guide: Wildflower Field Guide, North America at Flickr.
To add this to your blog, click Add New in the Plugins section of your blog’s admin screen and search for Wildflowerizer. The WordPress Plugin Directory has more info. If you install the plugin, please go there and give it a rating and compatibility feedback.
