boosters · 09-02-2008, 10:19 PM

I want to secure my html images on website. Suppose when someone try to click right click on my image than the pop will comes and shows the "Please don't save my images". how should i do. What the code ?.

javascript,
but a geek will always find a way to crack the measures.

To protect images, simply add a © -your name, your site name on the image. Be sure that the images originally belong to you.

The disabling right-click method can foll noobs but not people who are 'determined' to steal your image.

iMav · 09-02-2008, 11:05 PM

use watermarks+right click disable will definitely act as a deterrent

How about CSS Images ?
Define a CSS class and give it the property background-image and others.

Be sure to deny access to the CSS file using apache .htaccess

Code:

<FilesMatch *.css>
Order allow,deny
Deny from All
</FilesMatch>

Place the above code in the directory where you store the CSSes in a file called .htaccess

but if a person save the page on his HDD, then nobody can be stopped from accessing the images

not a very hard thing to figure out

THe best method I have found which is very secure & full proof is not put ur images on the web (public domain).....................nobody will see it ................hence nobody will want to steal it.

Rest all methods fail.

Web was meant for public sharing thats why its WWW.

suppose you store the images under a uncommon directory i.e. other than img or images ; and use CSS method, then how will you steal images ?

There is a software that do that here

There is also a script:-
Put this on <head> section:-

<script type="text/javascript">

</script>

and whre u insert image type this
:-
<img border="0" src="image path" onmousedown="whichElement(event)" usemap="#FPMap4"></p>

Hope it helps...!!!

The site : carmelite.netfirms.com is half made by me just visit there and goto Snaps section and right click the image.

In the last line of the HomePage see it is written:-

U seem to be ignoring the fact that css or no css the images still have to download to my computer & then I can do what ever I want.

Just go to IE temp folder & get the image...........................worse I can always take a screenshot.

Best method is not to post the image on the web.
Web is for showcasing & sharing not meant for securing, have u ever seen military maps on the web?
why not?

you can prevent caching also by the HTTP header definition no-store

It wont let u save the image in cache for sure but you can still get the image from the cache without closing the browser.
No cache is only meant that once the browser is closed the the image should be deleted.

U always have the print screen & if u can find a way to disable that then there are many softwares to record the screen....................u have to find another method to disable these software too..................so the moral of the story is either be on the web or don't be on the web.

^ but how about screenshot using printscreen?

hullap · 11-02-2008, 10:48 AM

apply a water mark.

Charan · 11-02-2008, 11:12 AM

eh? comeon guys , all the images are cached before rendering, Just looking into Cache folder of the browser will give everyimage loaded. Once its loaded into memory it can be copied by any means. bestway to protect you images will be either watermark or my having creative common licence to it.

@booster : stop wasting time to learn how to avoid people to copy your image. Learn how to make the copied image always show you name/site.

hullap · 11-02-2008, 11:26 AM

see my avatar iv taken it from here.http://downloads.manutd.com/graphics...ship%20Winners

What purpose is that CC license going to serve

? huh. even on CC license, if i copy an image and modify it using GIMP and use it somewhere else is it going to be found ?

So the moral of the problem is either don't place images on the web or don't try to protect them if placed.

CC licence allows you to show/distribute you work with peace of mind, if anyone tries to take advantage of your work then you can sue them. Its similar to GNU, wodnt FOSS comunity sue me if I use code which comes under GNU, modify it and sell it without GNU licence.

suppose if nobody is informed of the copyright infringement ?

Charan · 11-02-2008, 02:10 PM

.. dude .. thats the problem .. no matter what you do to protect you work it gets stolen. thats why the rules come in .. give your works with a rule. Microsoft does it with EULA , where as L!nux does it with GNU. in both case, if borken then the person can be sued. Finding out who broke it depends on the orginal author.

This non-caching feature is due to the HTTP header no-cache and no-store.

use Flash to embed images.

it will lead to running away of visitors as flash take much longer to load than normal images and also some visitors may not have flash player installed.

Even if we embed it, we can still capture the image using Print Screen!!!
