Here is a thread about the same subject:
<!-- BBCode Start --><A HREF="http://gallery.menalto.com/modules.php?op=modload&name=phpBB_14&file=index&action=viewtopic&topic=1924" TARGET="_blank">Image Protection </A><!-- BBCode End -->
Maybe that will help. Not sure tho.

most excellent script but i will work to find a way to use it with the post nuke set up. I would also like to find a way to insert a simple no right click script into the gallry files somehow so that each page it creates has no right click options. Any help would be much welcomed.
Thanks Glassdog

I understand, however, disable right click will not solve your problem. I could go to File : Save As, in IE and bring down the images also.
Let me know when you think you have it and I can test all the way to get images.
Thanks

There will always be a way to get the images i simple disabled the right click option to slow down the honest thieves :smile:. Worked well i put the no right click script in the index.php file for the gallery after the ?> tag so any time the gallery is open the right click option is disabled. I am still working on the script that was in the link you gave me. I will pass along the info when i finish it.

Thanks a lot

I used this script and you set it in the gallery index.php file at the bottom of the page after the ?> tag Simply paste it in and you are done
<script language=JavaScript>

function clickIE4(){

alert(message);
return false;
}
}
function clickNS4(e){
if (document.layers||document.getElementById&&!document.all){
if (e.which==2||e.which==3){
alert(message);
return false;
}
}
}
if (document.layers){
document.captureEvents(Event.MOUSEDOWN);
document.onmousedown=clickNS4;
}
else if (document.all&&!document.getElementById){
document.onmousedown=clickIE4;
}
document.oncontextmenu=new Function("alert(message);return false")

Think the javascripts seem essentially similar, except, the meta tag I insert, takes care of IE6 save image feature. Not my own idea, saw it some place! :wink:
Also, I have PHP code enabling the admin and the album owner to right click. Someone here had given me that initial seed for that idea. So, if anyone is interested, let me know (it is 2 more lines of code!)

These scripts are very basic methods. The user only needs to use opera or go veiw source and they can copy the picture easily. I did put a php script on the forum not long ago that stops anyone trying to take the pictures directly.
The no right click function is not the best way to go about stopping someone taking your pictures!

There is no way to stop someone from taking your the images you allow them
to view. It's simply impossible. The best you can manage is to prevent people
from 'leaching' them. I use a simple mod_rewrite .htaccess file in my albums
for this:
# No indexes allowed.
Options -Indexes
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteCond %{HTTP_REFERER} !^http://www.mysite.com/path/to/gallery/.* [NC]
RewriteRule .*.(jpg|gif|png)$ - [F]
</IfModule>
-- This is essentially the same as posted in the user guide someplace, add any other
extensions you need to the RewriteRule line for movies or whatnot. This is a better
solution IMO then trying to use scripts and java and so-on.

wich script you trying ?

I am setting up Gallery as an image library and so far the best way I have found to protect images is to batch process them with a transparent watermark. Can be done with Photoshop but I have started to use picture-shark which is specially made for the job.
I have seen other picture library scripts that can 'overlay' a transparent GIF over an image but I think I read even that method is not secure.
I sleep easier knowing that my images will be pixelated and covered in text if someone tries to steal them :grin: .
This is suitable for commercial sites only I guess.

If you do get the script to work please let me know how you did it.
Thanks

Ahhh, the forum ate my , the Rewrite Rule should be:
RewriteRule .*.(jpg|gif|png)$ - [F]
Although that shouldn't be the issue with you. Does your browser properly
transmit a Referer header?

Ok I am using IE 5.5 and nescape 7.0. The web page is postnuke 7.2.1 i have created a file named .htaccess and placed it in my albums folder with the following code
# No indexes allowed.
Options -Indexes
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteCond %{HTTP_REFERER} !^http://www.promochickmusic.com/modules/gallery/.* [NC]
RewriteRule .*.(jpg|gif|png)$ - [F]
</IfModule>
Still I cant get it to allow my browser to show the pictures can it be something in the way post nuke calls the module ??
see webpage at http://www.promochickusmusic.com

Just wanted to make a quick update i got it all worked out and running great thanks for all the help anyone needs the code to set on postnuke let me know

I posted a link to a perl script which would block direct access to your images based on the referer. It also allows you to specify a maximum file size. Both restrictions can be bypassed based on the client's IP.

Ok, I used the method posted on this thread but I wasn't able to get my images to come up...so I used the method from this URL: http://www.thesitewizard.com/archive/bandwidththeft.shtml
Apparently my pictures are working, but how would I go about testing this? Also in that URL it told me to put my .htaccess in the directory where the pictures were, but I wasn't able to upload the .htaccess in any specific album directory, just the general album directory itself...so would that be ok? Please help! Thanks in advance!
