您所描述的许多内容都可以使用 .NET 框架中提供的组件来完成。
我们使用 COM 版本的 ImageGlue 取得了巨大成功，并且发现它非常有用稳定有效。当有人通过我们的管理站点上传图像时，我使用 ImageGlue 生成缩略图并在存储之前调整图像大小。您还可以通过让图像标签引用类似 url 的方式动态地执行此操作
，并让图像页面或服务生成图像并将其流回浏览器。
这并不能解决内容交付网络等问题，但它相对便宜，并且可能会为您指明正确的方向。

This doesn't address issues like content delivery networks, but it's relatively inexpensive and might get you pointed in the right direction.
ImageResizing.Net 库提供 Amazon 与 CloudFront 兼容的动态图像调整大小 - 您可以立即调整大小的动态图像，以及边缘缓存的可扩展性和响应能力。
虽然核心库不受 MIT 约束，但云捆绑售价 99 美元（但包括源代码和再分发权）。
目前还没有托管服务版本，但可能很快就会有。 如果您希望更快地实现这个想法，请投票。

The ImageResizing.Net library offers Amazon CloudFront-compatible dynamic image resizing - you get instantly resized dynamic images, and the scalability and responsiveness of edge caching.
While the core library is MIT-free, the Cloud bundle costs $99 (but includes source code and redistribution rights).
There isn't a hosted service version yet, but there may be soon. Vote for the idea if you want it quicker.
