Anyone who doesn't like having their images pinned could add a code snippet to their web pages which prevents pinning.
It wouldn't stop the problem, but it would certainly slow it down.
No Pin Code
We have a small piece of code you can add to your website(s) to prevent pinning. Copy the snippet of code below and paste it into the <head> section of any page on your site.
<meta name="pinterest" content="nopin" />
When a user tries to pin from your site, they will see this message:
"This site doesn't allow pinning to Pinterest. Please contact the owner with any questions. Thanks for visiting!"
Advanced No Pin Code
You can customize the message to users by adding description to the meta tag:
<meta name = "pinterest" content = "nopin" description = "Sorry, this user does not allow pinning" />
You can also disallow pinning of a single image:
<img src = "foo.jpg" nopin = "nopin" />
In a perfect world something like this would not be needed but in a perfect world you wouldn't need a lock for your front door either.
In some niches, Pinterest can be a significant source of traffic. One of my clients puts sharing tools on every product page and they've had tens of thousands of visitors from Pinterest so far this year. Pinterest traffic converts at a lower rate than the site average, but they do buy things.
