How to prevent downloading images and video files from my website?
I have an HTML page which resides locally on my machine. I have 2 items on every page 1 - PPT presentation 2 - Video tutorial . I want to prevent users from downloading the content for their personal use. How can this be achieved?
Thanks in Advance !

Unfortunately the short answer is that it cannot not be done in a good way, if the content should be available at your website at the same time.
There are solutions where you obfuscate the path to the file when it is sent to the browser, and then use a JavaScript to "decrypt" the path at the client. But those solutions are in no way bullet proof, as the decryption technique would have to be sent to the client as well.
This one is not easy to do, especially if you show them on your page already. As you do so they'll get downloaded on the browser an there's no way, at least i'm aware of you could do this with ease!
All you can do is to make it harder... but it still always be possibile! Even if you could stop them from downloading the file, you can't stop them from hooking a VCR to their video card and re-recording it. Even if you use some protected-path technology to stop that, you can't stop them from pointing a camcorder at the screen.
Same applies to the ppt presentations... as they can view them... users could take screenshots or do whatever to create their own copy!

I am developing an universal windows app. I need to download a webpage and extract images from it.
I got the html code and extracted the links to images and downloaded them. The thing is, the site has infinite scrolling (like facebook). When I scroll down to the bottom it loads more images. I am not able to incorporate this into my app. I am a beginner and have very little knowledge of web development or windows app development. This is my first app. I am stuck and have no idea how to proceed. I don't want to use webview as it displays ads from the site and other unnecessary contents. I only want the links to those images. Please help me go past this situation. I need a way to download the new html content that the site loads when user gets to the bottom or some other way to get the image links.
Thanks in advance.
You may or may not be a me to implement this specifically because of the reason you stated. You need to determine how the site loads this information. First I would download Fiddler and in turn enable https connect logging so you can see your encrypted traffic going through Fiddler. Btw the Web View has events you can hook to see loading URLs, etc and it can also be hidden.
So again you need to first understand how the site you want to do this on works and emulate that, assuming they don't have an api already to give you this information as mentioned I'm the comments.
When you do that, come back with code examples and you'll get better help.

Modify permanently a CSS of a website that I do not own, and distribute the change to my network
(3 answers)
Closed 1 year ago.
My dad's company asked me to change the menu bar of their website. Basically, I just opened the page source (Ctrl + U) of the website, copied and pasted all the HTML and CSS to notepad++ and changed some of the HTML code (just to try it out and test it to see if it works) and saved it as an HTML file. But how do I permanently save the changes to the actual website so that everyone can see it? Sorry if this sounds like a noob question. My HTML skills are at beginner level.
It isn't possible to edit arbitrary websites. If it was, every major website would be covered in spam and pornography.
You have to have access to the server. The specifics depend on how the site is set up. There might be a content management system to edit it through, there might be a SFTP server you drop static files in, there might be any number of other approaches.
This desktop save isn't gonna work. You need access to the original files of the hosted website!
Like, if its a wordpress blog, you need to get access to its admin-panel
or if its a tailored website, you need to get its FTP access, then you can download that page, make changes and re-upload it on the same location - that's it!
Both require some credentials - for example if your website url is example.com, then it may be something like:
for wordpress: example.com/wp-admin/login.php
for site: ftp.example.com
The code you see on the browser are just built out of some raw data that are provided (sent) by the server for your browser. The browser engine makes its own version of source code from that data to be able to display the page to the end user. This code is most probably very different from the actual source code that the developers have written.
Also, You don't have the permission to change the website from your browser. You need to access to the server and make your changes from there.
Just like you can't make changes to a tv programme by changing the audio/video settings of your own television and you need to access to the devices in the studio to make real changes to it.
I am working a website, and I'm trying to prevent the video file to be downloadable.
I've already prevented the right click function, and I've used a webiste called http://htmlobfuscator.com/ that allows the source code to be very difficult to decipher. The only issue I now have remaining is the inspect element feature on browsers. Does anyone know of any way to prevent this? I know that someone is always going to find a way to download or capture a video, but I'm just trying to limit the spread of my videos.
Thanks for your help,
Stephen
There is no actually way of completely stopping someone, you could however as some have mentioned use something like Vimeo or YouTube to minimize the downloading of your videos, or another way you could do it and have found from personal experience is either creating a login/register on your site to make someone signup to get your video thus minimizing how many can download it or you can encrypt the video with a password, i believe Vimeo has this option which requires someone to enter a password in before even viewing the video.
Yet these are just two ways to Minimize not completely stop.
There is no way to stop a browser's document inspector from finding your file's location. However, I am a recording musician, and I know of a few things you can do to make thieving more difficult.
Put your JS video location in an external file. Not a lot of protection here, but worthwhile enough to add.
Break up the video location into a few different JS variables. Your thief would at least need some basic JavaScript knowledge to get to the video location.
Use an obfuscater, like you did. (I LOVE HTMLObfuscator!)
You could use flash video. This is difficult to download, but slower viewing, and also a bit more difficult to create and host on your website.
The best thing to use is streaming video, but not everyone is able to do that either.
Good luck!
I've made a website which displays images hosted on other sites using the html src="http://......" tag, however sometimes some of the images won't load. This appears somewhat random, and I don't think it is a problem with the links themselves.
I display a lot of images, so I am wondering if this is a common problem when trying to load many thumbnails from another site. Is the best solution to host all the thumbnails on my own server, and if so, is there an efficient way to do this (so I don't have to manually download and link to every image)?
Thanks
Is way better to host it on your own server.
Because if are all from other servers, you must connect to all servers and download it.
It causes worse response and increase the time required to load the page.
To the image and links downloading - I think it is possible, just go on google and try to find some advanced html page downloader. I had one and it worked directly the way you want. - can't remember the name..
(also sorry for my bad English)

Recommended way to embed PDF in HTML?
(30 answers)
Closed 9 years ago.
I want to show pdfs in certain pages on my site. I've experimented with google's viewer api and it works great but I dont want to depend on a third party api call. I also want it to be as robust and reliable as possible, so I'm trying to avoid javascript. I see some indication that it can be done with just HTML using either or tags, but there appears to be disagreement as to the browser support: Recommended way to embed PDF in HTML?
Is there a definitive way to do this?
I need to support IE8+ and the site will be responsive, so the solution has to be able to accommodate smaller screen sizes.
Attention duplicate police: The entire basis for this question is to figure out what is specifically NOT answered in the other question. I even linked to that question in my ow
If you don't want to use JavaScript -- no, there is not.
Even if there is a good enough solution for some OS with something like Acrobat Reader installed (maybe you get lucky with Windows), all the other OSes still don't support it.
So, if you want your site to be seen more or less the same way by everybody, you'll have to go with Javascript base things and their not so robust and reliable support -- they are pretty portable, that's a great thing on the web.
