For the WP OneDrive Gallery PlugIn i needed a simple tool to easily remove the ImageDescription Exif filed of the images, and add new description to the images.
This small tool help you to set this field very fast, just click on an image, and type the description, what immediately saved to the image.
The JSON caption creates a json file to every folder, and store the caption in this file for the images or videos, so the WP OneDrive Gallery can pick up the captions from this JSON file.
