render a view that has image links something like this
渲染具有图像链接的视图
<img src="http://www.yourwebsite.com/mycontroller/renderimageaction/imageid">
in the code of mycontroller, create a renderimageaction, in it go and look for image "imageid" in the database, read the image data, and return the data to the browser as a content-type "image/jpg" or other suitable type depending on what you have stored your images as in the database

Generate the image source point to a web url which will query the database and put them into the response stream with correct MIME type.
生成图像源指向Web URL,该URL将查询数据库并将其放入具有正确MIME类型的响应流中。
With Asp.NET routing you can even do something like http://somehost/image/logo.jpg where "image" is actually an action to pull the image from DB. This way the user can preserve picture name when they save picture to their local drives.
使用Asp.NET路由,您甚至可以执行类似http://somehost/image/logo.jpg的操作,其中“image”实际上是从DB中提取图像的操作。这样,用户可以在将图片保存到本地驱动器时保留图片名称。
