Adding the Javascript code to display a Pinterest Pin It button when your website visitor hovers their mouse over one of your sites images is easy enough and only requires about two simple lines of code you paste into your web pages html of wordpress template.

However the easy way is not always the best way. Any time you call code from another website you basically giving partial control of your website over to the website that's hosting the code. Now I'm willing to bet dimes to dollars that Pinterest is one of the most trustworthy web domains in existence however I personally prefer a Pinterest Pin-It button were the code is not called from Pinterest but resides 100% on my own website.

If you're as paranoid as me then the good news is this page contains the JavaScript code required so not only can you display pictures painted buttons on image hover what you can do so with 100% security because all the code and everything required resides on your server alone ...
