防止图像保存 [英] preventing images saving

问题描述

有没有办法防止（至少对于不那么高级的用户）

在本地磁盘上保存图像;目前我使用javascript处理

鼠标右键单击，但所需要的只是在浏览器中禁用js？


TIA

解决方案

简而言之，没有。


你可以有小技巧，ActiveX对象等......但事实是如果

客户端已经在查看您的图像，那么它已经在他的硬盘上了，在短期缓存中至少是
。

在本地磁盘上保存;

是的。首先不要上传图片。


否则，如果你想让人们看到它，那么他们已经下载了它。

这就是互联网的运作方式。

其他人都是对的，你不能。但是我想你已经知道为什么你说对于不是那么先进的用户这是什么。除了JavaScript之外我还有其他想法可以帮助我们：b
$ b *为你的图像添加水印，以便明确它们的来源。


*在所有图像的顶部放置一个透明的GIF，所以右键单击

下载gif而不是他们看到的图像。


希望这会有所帮助。

hi, is there some way to prevent(at least for not so advanced users)
image saving on local disk; currently i use javascript which handles the
right mouse button click, but all it takes is to disable js in the browser ?

TIA

解决方案

In a nutshell, no.

You can have little tricks, ActiveX objects, etc... but the fact is that if
the client is already viewing your image, it''s already on his hard drive, at
least in the short-term cache.

saving on local disk;

Yes. don''t upload the image in the first place.

Otherwise, if you want people to see it, then they''ve already downloaded it.
That''s how the internet works.

The others are right, you can''t. But I think you already know that which is
why you said "for not so advanced users". Beyond JavaScript other ideas I''ve
come across which might help:

* Watermark your images, so its clear where they came from.

* Put a transparent gif over the top of all your images, so a right click
downloads the gif and not the image they are seeing.

Hope this helps.
