When to use this example

From the AI Image Describer: Captions, Alt Text & Tags readme:

What if a field is empty?

visibleText is null when the image has no readable text. If an image could not be downloaded or read, status is error and error says why (not found, refused by the site, not an image, unsupported format, too large); those rows are not charged.
