推荐答案

如果图像本身在数据库中，这就变得棘手了。您无法将图像放入网页。你必须引用它们，例如< img src ="链接到图像" />

If the image itself is in the database this gets tricky. You can't put images into a web page. You have to reference them such as <img src="link to the image" />

您需要的是另一个页面，其中绝对没有HTML代码。这个其他页面必须访问数据库，根据传递给它的一些信息获取图像，然后吐出图像并设置approrpriate响应头，以便浏览器
知道它是一个图像。你的图片html标签看起来像< img src =" imagehandler.aspx？imageid = PRIMARYKEY" />其中主键是带有图像的数据库行的主键。

What you'll need is another page with absolutely no HTML code in it. This other page must access the database, get the image based on some information you pass to it, then spit back the image and set the approrpriate response headers so that the browser knows it's an image. Your image html tags will look like <img src="imagehandler.aspx?imageid=PRIMARYKEY" /> where primary key is the primary key of the database row with the image.

以下是在VB.Net中完成的示例：

Here is an example done in VB.Net: http://www.velocityreviews.com/forums/t78173-display-an-image-from-access-database.html

这个的响应类型是BMP，您需要将其更改为您的图像类型。例如JPG，PNG等。您还需要确保图像是Web友好的，因此BMP或TIFF将无法显示。

The response type for this one is BMP, you'll need to change it to your image type. such as JPG, PNG, etc.. You'll also want to make sure that the image is web friendly so a BMP or TIFF won't be acceptable for display.
