使用集合让一切井井有条
根据您的偏好保存内容并对其进行分类。
创建一个 ID，用于呈现包含合集中多个图片的图片。
此属性与 GetFilmstripThumbnailPixels 结合使用。调用 filmstripThumbnails.create 会提供一个表达式和一些输出选项。filmstripThumbnails.create 的结果是一个 ID，表示在对该表达式求值并应用这些选项后得到的图片。随后，可以调用 GetFilmstripThumbnailPixels 来获取显示 ImageCollection 的所有元素的图片，这些元素会从上到下或从左到右串联。该 ID 的有效期为中等时间（几小时）。
请求的总大小限制为 ImageCollection 中的所有图片的 512*512*100 像素。超出这些限制的请求将导致错误代码为 400 (BAD_REQUEST)。
