++Best idea to protect image ,can anyone code this++

I wil start with one example
suppose my website is example.com
my image name is dp.jpg
the image dp.jpg is on the folder images_uploaded/images
so i can access the image through

http://www.example.com/images_uploaded/images/dp.jpg

Code (markup):

so to insert that image i need to enter the following code

<img src="http://www.example.com/images_uploaded/images/dp.jpg">

Code (markup):

If we can create a php file called showimage.php
and if we use

<img src="http://www.example.com/showimage.php?(some random string)/images/dp.jpg">

Code (markup):

then it should show the image

http://www.example.com/images_uploaded/images/dp.jpg

Code (markup):

if some one copy the image location which is

http://www.example.com/showimage.php?(some random string)/images/dp.jpg

Code (markup):

it should show only some error mesage or some thing but not the image

so the users will not able to find the real directory name which the image contain

so can some one develop a php file called showimage.php which works like i explaned above

Thanks in advance

 

Hey, the script showimage.php is going to be very simple but if a user points her/his browser to http://www.example.com/showimage.php?(some random string)/images/dp.jpg they will still get the image...

 

when some one goes to that image location then he will see only some text like the below

Code (markup):

i saw this type in some capcha
so i am sure some one can make it

 

The thing is, the script you are talking about is not sending JPEG headers to the browser so the browser shows the image as a string of text. This is a big defect i that script.

To make it work on all the browsers and be valid you must send JPEG/GIF/PNG etc. headers and unfortunately the browser WILL display the image...

 

yes i need that
so the random string once loaded cannot be re used
if i blocked right click and drag
no one can save it
and also
users cant use the link from view source to save the image
so it is 99% protected
the only way is print screen
but they will not get the full resolution
so please some one code it

 

This will protect the images_uploaded folder for sure...

 

not protected 99%
you can reload page(download html code) and will get new link not used
and download the image

 

when someone use the image code direct he will only get a page with
some codes like this

PHP:

 

use ajax, surely it will hide the code inside the container

 

The "some code like this" you are talking about is actually the image.. just in a binary or textual representation because the appropriate headers haven't been sent. Anyone savvy can just save that as a jpg.

 

You can save that as image using browsers

So no protection is there.

 

This is a different approach

On all your pages start a session and set a variable when the page has loaded like this.

<?php 

   session_start();
   $_SESSION['last_page_load'] = time();

?>

PHP:

Then you create a script with the following code

<?php

   session_start();

  $seconds = 20;   

   if (time() - $_SESSION['last_page_load']< $seconds) {
      $file = substr($_SESSION['REQUEST_URI'],-3);
      header('Content-type: image/'.$file); 

    echo file_read_contents($_SESSION['REQUEST_URI']);
    exit;

 }


?>

PHP:

Then add a redirect rule for all images to this file like this

RewriteRule ^images/(.*)$ http://www.mydomain.com/imagecheck.php

Code (markup):

This means that all images actually will be loaded via the imagecheck.php file.
All requests to the images that are later than 20 seconds after the last page load will load nothing.

NOTE:
I have not tested this script so not sure if it will work but it should with some testing and debugging.

 

Is this method really necessary to put a random code in the call to an image file? Why not just use an Apache server and edit your .htaccess file to prevent others from hotlinking your images?

RewriteEngine On
RewriteBase /
RewriteCond %{HTTP_REFERER} !^$
RewriteCond %{HTTP_REFERER} !^http://(www\.)?example.com/.*$ [NC]
RewriteRule \.(gif|jpg|swf|flv|png)$ /feed/ [R=302,L]

Code (markup):

See hxxp://www.askapache.com/htaccess/mod_rewrite-tips-and-tricks.html#prevent-hotlinking for more discussion about using mod_rewrite.

 

please explain the steps in detail
thank you for the fast response

 

If you want to allow users to see the image in the browser but prevent them from downloading the image, I have some bad news for you.

 

why dont u use ur apache server's hotlink setting so that no one can access the picture outside of ur own server. ... and for browsers being able to save the jpg as image, u can easily avoid it by taking a div tag equal to the image size and then use its background image property to load the image.. that way no one will be able to save it as picture anymore or do any dragging or whatever...
let me know if it helps...

 

i need it for applying on a dynamic site not in static
and also i know hotlinking but
i using the same images on morethan one site
so please read my thread main post and then you can understand my idea
i hope it can be happen
but i don know much php to code such an idea

 

That's easy. You can still use the hotlinking code I displayed earlier. All you have to do is add as many URLs as you want. Using the same images on more than one site is not a problem.

 

Please suggest some php code for the main post on this thread
that is for my idea
i need a working php file for my idea

 

Hi,
Please check these links and if you interested in pm me?
dailyfreelink.com/contact.php (You will see a security code whose link is dailyfreelink.com/images/securityImage.php)

Then when you copy and open image path with browser as dailyfreelink.com/images/securityImage.php
You will see a message as "You have no privilege to access this item"

is it ok?
