保护ASP.NET中的图像 [英] Protecting Images in ASP.NET

问题描述

我知道不可能完全保护网站上的图像

所以没有人能够得到它们。但是必须要有很多方法可以阻止人们窃取图像，并使图像被盗更加困难。我目前正在使用没有右键单击

javascript函数，但是有没有更多方法可以阻止人们从b
窃取图像？

欢乐

解决方案

您可以尝试通过ihttphandler管道gif等请求

检查了引用并拒绝那些未在您的服务器上作为整个

页面请求的一部分的内容。

您也可以将图像剪切到喜欢的位置并将所有部分放入一个

表中。用户应该单独下载所有部件，并在加入所有请求时。


您还可以创建getimage.aspx？img = name& code = id，这将返回

每个给定代码只有一次图像。并禁用任何缓存。

Hi,

I know that it is impossible to completely protect images on websites
so that no one can get their hands on them. But there have to be a
lot of ways to deter people from stealing images and make it harder
for the images to be stolen. I am currently using the no-right-click
javascript function but aren''t there more ways to deter people from
stealing images?

Joy

You could try to pipe requests for gif etc through an ihttphandler that
checked the referrer and rejected those that did not come as part of a whole
page request on your server.

You can also cut image to the pleases and put all part''s in to one
table. User should download all parts separately and when join all pleases.

Also you can create getimage.aspx?img=name&code=id, which will return
image only once for each given code. And disable any cache.
