We recommend jQuery Pin It Button for Images to display a pin it button over your images.
How to Use Your Own Pin It Button
After installing the plugin, on your WP Dashboard, navigate yourself to Settings >> jQuery Pin It Button For Images Lite.
Click the “Visual” tab.
Scroll down to where it says “Pin image”. The default settings look like the following.
To use your own button, select “Custom” and click “Upload an image using media library”.
You can either upload a new image or use one from your library. Choose the image you want to use, and click “Use as Pint It button”.
You will see your new button on the preview. Click “Save Changes”.
How to Disable Pin It Button on Small Images
I personally only like the Pin It button on large images, because I think it doesn’t look good when it overlaps small images.
Go to the “Selection” tab.
Scroll down to where it says “Minimum image resolution”.
You can decide your own minimum size of the image for the pin it button to show up, both on computer and small devices. I choose minimum 500 x 500 px for images on the computer and 250 x 250 px for images on small devices.
Finally, click “Save Changes”.
