How does Smush.it handle the image copyright?
Yahoo! is committed to respecting the rights of owners of creative works. You may only use the Smush.it service to optimize images that you have the rights to modify or change. Many images that you may use on your site, especially those from feeds or image services, may have specific requirements regarding keeping certain portions of the metadata such as the copyright notice. You should ensure that you have satisfied these requirements before you optimize an image. Smush.it currently keeps all JPG metadata and exif (exchangeable image file format) information. We are investigating how to leave the copyright field in place while removing the other metadata (for example: camera information, audio files, thumbnails, and so on).
