| 5 | 5 | The filter is working as designed on my tested site, but note the intent of `big_image_size_threshold` is to save ''bandwidth'' not ''disk space.'' The original image **is still saved** when `big_image_size_threshold` is nonzero (the default), and its short filename is put into the metadata as "original_image." The "-scaled" version of the image though is the one used by WP when you ask for the image while editing pages, etc. There's a link to the original file in the Dashboard / Media view of the image, in the metabox. |
