Just ran into a problem while using Access-Aide to fill the alt-text for an ebook that contained 145 images. The plugin worked wonderfully well after using exiftool to populate the AltTextAccessibility field in the image metadata.
But then the author sent a new file of corrected alt-text descriptions, without highlighting the corrections. So we had to repeat the process.
BUT the Access Aide plugin only works if the existing alt="....." is empty.
Is is possible to indicate to the plugin, that it's OK to overwrite any existing alt-text entries?
I did use a regex work around to remove the existing alt-text, but not being a frequent regex user, there were a couple of issues to solve.
