Here are some directions:. Again, I repeat that none of this will stop an experienced user from grabbing the content e. Sometimes it's as easy as using the browser's developer tools or using the website without JavaScript. Yet, it will give inexperiences users a hard time, so they may look for some easier source to grab from.
Also keep in mind that the above techniques will affect search engines when reading the page's content if you're interested in blocking them, start with a robots. I'd like to add a more philosophical comment. The whole intent of the internet, particularly the World Wide Web, is to share data. It's really that simple.
Too many people think they can impose their own rules on an existing design. Those who want to post content on the web, and control its distribution, are looking to have their cake and eat it too. If you are using PHP, the best way is to control it the. You can also have a look at my question and the accepted answer here for more tricks on the browser side. In short, no. If someone can view an image or video in their browser then they have, by definition, downloaded it.
That's how the web works - it is client server based. Whatever you can view in your browser client has been transfered to your computer from the remote website server.
You didn't really say, but I'm guessing you are having problems with people deep linking into your content. If that's the case, and you are open to server side code, I believe this might work:.
But it's a general outline of a workable process which might help you prevent users from deep linking. You can overlay images with a transparent div , which will prevent people from right clicking on them or, setting the background of a div to the image will have the same effect. If you're worried about cross-linking ie, other people linking to your images, you can check the HTTP referrer and redirect requests which come from a domain which isn't yours to "something else".
It also doesn't hurt to watermark your images with Photoshop or even in Lightroom 3 now. Make sure the watermark is clear and in a conspicuous place on your image. That way if it's downloaded, at least you get the advertising! No it's not. You may block right-clicks and simillar stuff but if someone wants to download it, he will do so, trust me ;.
As soon as they view your page that includes the picture or video, the item is downloaded into the temporary folder of their browser. So if you don't want it downloaded, don't post it. You can mark folders or files so that they don't have read access any of the main web servers support this. This allows you to store them on the server without any level of access to the outside world. You may want to do this if you have a service that generates images for someone else to download later, or if you use your web account for FTP access, but don't want anyone to view the files.
However, as others have said, getting into copyright areas where people can view the image or video but not save them locally is not fully possibly, although there are tools to discourage illegal usage. Plus, it will provide a better streaming experience for your users without the need for a separate streaming server.
Granted that any image the user can see will be able to be saved on the computer and there is nothing you can do about it. Now if you want to block access to other images that the user is not supposed to see, I am actually doing it that way:. Div overlaping or background pic setting but users with little sense can easily save all resources by opening inspect element or other developer option. This will remove any click functionality from a page, but it sure stops people stealing any content!
If you want only authorised users to get the content, both the client and the server need to use encryption. For video and audio, a good solution is Azure Media Services, which has content protection and encryption. Get certified by completing a course today!
