Usually I answer most of questions in more or less fine detail, so I''m sorry that I don''t do it in this case. The reason is: this question is way, way too popular, and CodeProject keeps many answers to it, answered again and again. Please, just look here:
http://www.codeproject.com/search.aspx?doctypeid=4%3b5&q=database+%28image+OR+picture%29+%28store+OR+get+OR+retrieve%29[^].

That''s over thousand results, and many answers are detailed enough.

Good luck,

由于它是一个网站，您需要编写一个HTTP处理程序来处理包含标识您图像的ID的URL。然后，您查找图像并返回图像的字节，以便您可以在img标记中使用该URL。关于如何做到这一点的文章很多。

As it''s a web site, you need to write a HTTP handler that handles a URL which contains an id that identifies your image. Then you look up the image and return the bytes of the image so that you can use that url in an img tag. There''s tons of articles on how to do that.
