The Tumblr Share button lets Tumblr users easily reblog content from sites outside Tumblr. Now you can easily insert a Tumblr share button on your WordPress blog with a plugin.
The Tumblr Button for WordPress gives you the option to select from a number of different buttons in the settings:
Once you’ve chosen your button, it will be automatically added to the bottom of your posts. When a visitor clicks on the button it will launch a pop-up window where he can log in to Tubmlr and then share your content as a Text, Photo, Quote, Link, Chat, or Video.
The user will be able to tag it, publish it immediately, save it as a draft, or add it to the queue. If you have active Tumblr users visiting your site, this button is an excellent way to give your site more exposure on other blogs.
