Resize images on the fly! Great for theme developers who add image sizes to their theme after image assets have already been added to the image library – images come out the right size, every time.
Works great for both single-site and multi-site installations. Multi-site installation requires SUNRISE to be set and wp-content/sunrise.php to be populated – Instructions are given within the plugin.
