WordPress HeartbeatA new feature in WordPress 3.6 is an upgrade to the autosave functionality that’s been around for years.

Strip Extra ImageScaler Attribute from Plugin-Generated Code

I am using the ImageScaler plugin for WordPress on a project, and I like what it does, but it adds a non-standards-compliant attribute to images, such as:

<img class="" src="http://www.example.com/imagescaler/generated-image.jpg" alt="Example" width="258" height="234" imagescaler="http://www.example.com/imagescaler/original-image.jpg" />

add_filter('the_content', 'strip_imagescaler');
function strip_imagescaler($content) {
	$content = preg_replace('/imagescaler="(.*?)".?/s','', $content);
	return $content;
}
