控制从站点复制图像 [英] controlling the copying of images from a site
问题描述
您好
有没有办法阻止用户从网页上复制完整尺寸的图像。
显示宽度和高度较小的图像只影响图像
如图所示，仍然会下载实际的完整尺寸图像文件。我知道我可以通过两个版本的图像，一个完整的尺寸和一个
较小的显示用途来绕过它。但有没有办法得到两个图像的
并使用完整的ssize并停止复制或复制
只会是缩略图？
提前感谢

是的，不要在网页上放一个完整尺寸的图片。
（实际上，你可以使用Flash并在运行时动态加载图像
时间。图像在缓存中，但不是用户可用的格式。
但是，它们总是可以只是拍摄屏幕并以这种方式偷取它所以
最好假设你根本不能这样做。
< blockquote>嗯...你的信息没有多大意义..
但答案是否定的。
我认为你要找的是转移，而不是复制。
如果您不想发送全尺寸图像并在
客户端结束时调整大小（带宽）和别名问题），你需要转移
单独的缩略图。当然，缩略图可以在
上生成（并缓存在你的服务器上）。然后当客户端请求
全尺寸ver时，将它们发送给全尺寸v这个问题是什么？

Hello
Is there a way to prevent users copying a full size image from a web page.
Displaying the image with a smaller width and height only affects the image
as viewed, the actual full size image file is still downloaded. I know I can
get around it by having two versions of an image, the full size one and a
smaller on for display purposes. but is there a way around having to have
two images and use the full ssize one and stop it being copied or if copied
will only be a thumbnail?
thanks in advance

(Actually, you can use Flash and dynamically load the image at run
time. The image is in the cache, but not in a user usable format.
But, they can always just take a screen shot and steal it that way so
it is best to assume you can''t do it at all.
well... your message doesn''t make much sense..
But the answer is no.
I think the word you''re looking for is "transfer", not copy.
If you don''t want to send the full-sized image and resize it on the
client''s end (bandwidth and aliasing issues), you''ll need to transfer
separate thumbnails. Of course, the thumbnails can be generated on the
fly (and cached on your server). Then when the client requests the
full sized ver, send them the full sized version.
What''s the issue?
