It now includes the ability to take EMPTY alt attributes and look up the image's own metadata for XMP AltTextAccessibility or failing that, exif ImageDescription to auto fill alt attribute values.
It will NOT overwrite any existing image alt value. |
Many thanks for this, Kevin. I just tested it on an epub that had about 50 images with alt-text entries in their metadata. I removed the alt-text in the HTML code for one of the images and ran the plugin. But the plugin failed when it came to the page containinf the image alt="".
Here is the error log for that image.
