# Google 图片中的图片权限元数据
摄影师、摄影机构和其他相关行业会在图片元数据中提供有关图片的信息。Google 图片会尽可能在搜索结果中显示 [IPTC 元数据](https://iptc.org/standards/photo-metadata/iptc-standard/)。
### 添加图片权限元数据
* Google 支持使用 [IPTC 元数据格式](https://iptc.org/standards/photo-metadata/iptc-standard/)管理图片版权信息。
* 您可以直接在图片中嵌入元数据，也可以将元数据添加到一个单独的文件（称为[辅助信息文件](https://en.wikipedia.org/wiki/Sidecar_file)）中。Google 建议在图片中嵌入元数据，因为这样有助于防止元数据丢失。
* 尽可能尝试指定 IPTC 字段[创作者](https://iptc.org/std/photometadata/specification/IPTC-PhotoMetadata#creator)、[图片出处](https://iptc.org/std/photometadata/specification/IPTC-PhotoMetadata#credit-line)和[版权通知](https://iptc.org/std/photometadata/specification/IPTC-PhotoMetadata#copyright-notice)，以注明正确的图片来源。
我们建议您使用[元数据管理软件管理图片元数据](https://iptc.org/standards/photo-metadata/software-support/)。
### 是否可以移除图片元数据？
移除图片元数据可减小图片文件大小，从而加快网页加载速度。不过您应当谨慎，因为在某些管辖区，移除元数据可能是非法的。图片元数据可在线提供图片版权和许可信息。Google 建议您至少保留与图片权限信息和标识相关的关键元数据。例如，尽可能尝试保留 IPTC 字段[创作者](https://iptc.org/std/photometadata/specification/IPTC-PhotoMetadata#creator)、[图片出处](https://iptc.org/std/photometadata/specification/IPTC-PhotoMetadata#credit-line)和[版权通知](https://iptc.org/std/photometadata/specification/IPTC-PhotoMetadata#copyright-notice)，以注明正确的图片来源。
