My images have alt attribute, but is not showing. My SEO pluging does not recognized them and google prensets the an alt text that is not the one I wrote but the name of the picture(file). this is how it I can see it in the backend: [wpd_image_box thumbnail= ..... If I change it to [vc_single_image image= then the seo pluging, will reconizg it, but I will loose the theme in it.
