从Amazon S3提取图像

Question

I upload full sized images to Amazon S3 from my rails app. Is there anyway to pull thumbnail sized versions instead of the full image as the images are quite large? Or do I have to also upload thumbnail sized images to be able to do this?

Answer 1

您将需要在S3上存储要检索的尺寸，或在S3上创建一个图像服务器，该图像服务器将处理调整大小逻辑以提供您请求的尺寸。

Answer 2

您需要上传缩略图。
