Alt Text Missing for Pinterest Button

For the Pinterest share button that appears at the bottom of blog posts, there is no alt text for the image. For SEO purposes, there should ideally be alt text for this img tag.

As a temporary solution on one of our sites, I have added the alt text via a template override by editing /components/com_easyblog/themes/wireframe/socialbuttons/pinterest.php

Can you please look into fixing this bug for a future release so that a template override isn't needed?
