From the start we always felt that we needed to do something about the slow loading of the hashimage plugin. Today we have updated it with the option to use async loading, letting all the heavy work to be done after initial page load. See the settings page for this new option.
In this update we have also integrated support for pic.twitter.com and images in the lightbox are no longer cropper and cut, say hallo to the whole image scaled down.
As usual, you find this amazing plugin in the WordPress Plugin Directory and please leave a comment if you have any suggestions or just like the plugin.
The new latest version is 2.3.0.
