I'd like to make my site uncopiable by default, with the possibility of making some pages copiable. I've tried the standard browser-specific fixes but they don't see to stick. Any idea what I'm doing wrong/how to do it right? I.e.:

What do I need to put in.
Where do I need to put it.

Thanks.

You might want to ask this over at Wordpress.org and you might look for a plugin.

This is not a theme related question since if you swap themes you would want the same thing.

There are plugins that you can install to prevent casual visitors from copying the elements on your page. Most work by disabling the right-click of the mouse. However, that won't stop users who are determined to capture the content. If someone really wanted an image on a page, for example, they could view the source code (no way of preventing that from happening) and get the direct link. Or they can retrieve the image from the browser cache. Or they could use a screen capture extension that takes a snapshot of the browser window and saves it as an image file.
