My images have the ‘Alt Text’ attribute assigned in the WordPress Gallery screen, but the it is not added to the full size Gallery Image. I need this information to be part of the full size images for Pinterest. Am I missing a checkbox somewhere?
I tried setting the “Single image title” and “Gallery image title” to “Image Alt Text” but that didn’t make any change the the img alt attribute of the Gallery Image.
Confirmed this is a problem. A WordPress Gallery with alt and title tags added to the associated media do not display any alt tags for the image. When this plugin is disabled, the alt tags show up fine in the source code. Reactivating the plugin causes the alt tags to disappear again.
