          <p>本篇对照片管理的方式和服务进行讨论，主要讨论的是会对照片进行检索的管理工具，例如百度云和<code>OneDrive</code>只提供存储，而不对照片进行索引分类，提供管理的服务不在本篇的讨论范围内。目前支持照片管理的，之前Facebook在国内出过一个软件<code>彩色气球</code>，目前已经下线。还有就是<code>腾讯微云</code>好像也对照片也有一些管理功能也不在本篇的讨论范围内。本篇主要侧重讨论两种照片管理服务,一个是<code>Google Photos</code>还有就是<code>iCloud</code>的<code>Photos</code>。</p>
