Pinterest images on page are not showing

Question

I am trying to add a Pin it button on a blog page. AddThis widgets are being used for this.

But when I try to use the PIN functionality then it is not choosing all the images on my page.

The image tags are as below

-- Getting Pinned

<img src="images/blog/123_3710961211.jpg" class="blog-main-img">

-- not Getting Pinned

<img src="data:image/png;base64,v2nv1jcqS/VEhanlIJN8hnyDHoT4Z8FfAhX/g8EI9yHfLfPFQAAAA
BJRU5ErkJggg==" data-filename="Victor Vasarely positive negative space pic.png" 
style="width: 521px;">

Let me know what is the error? Is it that Pin does not include Data images? I have tried using another widget also but same result there.

I read somewhere that img size should be at least 100×200 but all my pics are greater than that.

Answer 1

pinterest does not support pinning from base64 images, you should be able to set a meta tag to an actual image not displayed on the page however

<meta property="og:image" content="http://example.com/pic.jpg" />
