Just wanted to get some input on best way to do a prevent right click on a RN Nuke site? on other cms they have a extension which works nice, but here I would imagine it would be to add a snippet of code. Question is, what file in RN would be best to add it to, and anyone have any handy code they can post 
Best,
jc |

You might not want to hear this , but i suggest you not use such code.
Disable rightclick is totaly useless and most of all , verry anoying.
It prevent users to open links from your page in another tab or window.
It prevents to 'simply' copy a text , what could be used for whatever , let's say do a search on google with it.
And atleast , it doesnt prevent anything to block someone from grabbing your content.
The list might have do's and donts , what is your intention with it , is it something specific? |

you can probably just find a JavaScript that will disable right-click, but I've never been a real big fan of that, as I use right click to navigate for new tabs (at times).
Is this to protect images? If so, I would look at either watermarking the images or overlaying them with a transparent image.. so if someone does right click -> save as, they just get the transparent image. Not full-proof, but will discourage most users.
here is an example of an CSS technique ()
if you try to save the images you will see what i mean  |

spasticdonkey, thanks! that would be perfect. Yes it is mostly for images. What files in RN would be best to or should I edit for method 1? |

No easy way to implement site-wide, as it requires changes to the code. I'm not real familiar with coppermine, might take some work to implement, but it's possible.
You need to know the height and width of the image. So something like this:
<img src="'.$url.'" width="'.$width.'" height="'.$height.'" />
becomes
<div style="width:'.$width.'px; height:'.$height.'px;background: url('.$url.');">
<img src="SomeTransparentGIF.gif" width="'.$width.'" height="'.$height.'" />
</div>
I would only bother implementing for large images, no sense going thru the trouble for thumbnails.. Probably a good idea to make note of your changes too, if you need to update coppermine later. 
Also note that anyone familiar with html can look at the code to find the image... If you display an image on a webpage it's impossible to completely protect it, without physically altering it with a watermark.
If coppermine does not include width/height for the image you could probably add a little php to retrieve them, something like
BTW, the above example does not add a watermark (or actually simulate a watermark, the image remains untouched), but you could tweak to do so..
CSS
| Code: | .watermark {background:transparent url(path-to-your-watermark-image.png);}
.makeopaque {
/* for IE */
filter:alpha(opacity=90);
/* CSS3 standard */
opacity:0.9;} |
<div class="watermark"><div class="makeopaque" style="width:'.$width.'px; height:'.$height.'px;background: url('.$url.');">
<img src="SomeTransparentGIF.gif" width="'.$width.'" height="'.$height.'" />
</div></div>
Another side effect of this method is the image will usually NOT display when printed either... Unless the user wants to use $5 worth of ink to print the page, and has "print background images" = ON |

Are you sure Coppermine doesn't already have a watermarking feature? |

Morning everybody
Neapolitanworld
I created my own NO RIGHT CLICK long time ago. This is a very funny and painful no right click, working on FF and IE.
Create a norightclick.js and upload it to your root where config.php is
| Code: | <!--
zaehler=0;
function right(e) {
if (navigator.appName == 'Netscape'){
if (e.which == 3 || e.which == 2){
alert("Here at MYSITE is not allow right click on the mouse");
for(i=0;i!=zaehler;i++)alert("I told you very clear, I will punish you with \n "+(zaehler-i)+"\n clicks.");
zaehler+=20;
alert("Next Time will be worse");
return false;}}
if (navigator.appName == 'Microsoft Internet Explorer'){
if (event.button == 2 || event.button == 3){
alert("Here at MYSITE is not allow right click on the mouse");
for(i=0;i!=zaehler;i++)alert("I told you very clear, I will punish you with \n "+(zaehler-i)+"\n clicks.");
zaehler+=20;
alert("Next Time will be worse");
return false;}}
return true;
}
document.onmousedown=right;
if (document.layers) window.captureEvents(Event.MOUSEDOWN);
window.onmousedown=right;
// --> |
call this script from header.php
?>
<script type="text/javascript" src="norightclick.js"> </script>
<?php
I hope you like it. Let me know
This is for the entire site. |

no right click =
It just doesn't work. Try it in the Opera browser 
Try Ctrl+I in Firefox, go to the "Media" tab and click [Save As...]
In Internet Explorer see the image toolbar on images or just open your "temporary internet files" folder |

unicornio, 
I love it! lols
finally got some time to add this...funny!
I noticed it only works when the user is logged in. This is still good for me since my gallery is only visible to registered.

One thing you might want to look for, and use a right click menu. It's the same amount of security as having no-right click.
If this is for images, then one thing you could do is force a watermark with gd.
I'm thinking about writing an addon for nuke that parses image codes before the source is pushed out, then uses it's own parser to change the links to a watermark all images module, which will hide the real url of the image, and force it to be an image with a watermark over it. |

use gd image to cut the image in several parts during parsing .
edit ;: just realised this was right click posts...
Oh... bad idea , right clicking *new tech* and rather good and well implemented on some sites.... i suggest you use some server side prevention rather than client side. |

That's easy with htaccess.
Just route thru a php script that detects if you're a valid member then fpassthru() the image
inside coppermine directory |
| Code: |
RewriteRule 'albums/(.*)' security.php?img=$1
