推荐答案

禁止用户从您的网站下载任何内容是不可能的。您不了解一个非常基本的事情：只要在用户的计算机上呈现某些内容，所有内容就已存在。禁止任何事情为时已晚。



此外，即使可以阻止从网站下载任何内容，也会严重违反用户权利。所有站点都允许按定义下载内容，但可能会限制其使用。用户合理地期望从您的网站获得相同的内容。



是的，我了解图片使用可能会侵犯其创作者的版权。通过宣布您和用户的权利，提供有关内容合法使用的公开信息，以及可能由执法部门（实际上非​​常困难）来解决这些问题。为图像添加水印有助于合法保护图像。

Prohibiting the user to download anything from your site is impossible. You don't understand one really basic thing: as soon as some content is rendered on the user's computer, all the content is already there. It's too late to prohibit anything.

Also, even if preventing downloading anything from the site was possible, it would be a pretty brutal violation of the user rights. All the site allows to download content by definition, but may limit its use. The user reasonably expects the same from your site.

Yes, I understand that an image use can violate the copyright of its creator. Such problems are solved by just declaring your and user's right, providing open information on the legal use of the content, and, possibly, by law enforcement (which in practice would be very difficult). Watermarking the image can help protecting it legally.
