alt attribute on img class=”GraphImage” element

Hi, for SEO reasons, it should be better if you consider to add the alt attribute event on the img elements with class=”GraphImage” and opacity = 0 that are overlayed on each thumbnail. We temporarily added the attribute with a placeholder value in class-wis_instagram_slider.php file.

Do you think this feature could be included on a future release of your plugin?

Thank you very much.
Regards.
