I want to make an image grayscale and had been looking at this: http://ottopress.com/2011/customizing-wordpress-images/

However wp_load_image is now deprecated and the recommended method is to use WP_Image_Editor

http://make.wordpress.org/core/2012/12/06/wp_image_editor-is-incoming/

I want to use imagefilter() on the loaded image but the image property is protected in the WP_Image_Editor class

Any ideas?

thanks
