Social Image Hover for WordPress has been pushed with a new update! Version 3.1 of the WordPress plugins adds another new button to include Tumblr support. If Tumblr is not up your ally there are also some other great benefits to v3.1 including a streamlined JS core, and better compression of the TC hover sprite image for social icons.
As always current buyers can download the update for free from their CodeCanyon dash.
The jQuery version will also be updated with Tumblr support in the coming days.
