Media images not showing in custom module

I have a problem, I have created a custom module in my Magento site, so in that module I’m calling custom attributes to display some content and images, but when I’m adding media image in this attribute image never shows on the frontend. In inspect element I can saw image in this format. Any suggestion?

<img src=”data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAEAAAABCAQAAAC1HAwCAAAAC0lEQVR4nGP6zwAAAgcBApocMXEAAAAASUVORK5CYII=” data-amsrc=”{{media url=” wysiwyg=”” img-pages=”” 2017device-benefits2.jpg”}}”=”” style=”margin-bottom:10px;” width=”80″ height=”45″ alt=”Benefits”>

Thank You
