Several thumbnail renditions of the original image will be created by the workflow. And once they're published, I can download any of those thumbnail images by adding "/jcr:content/renditions/<thumbnail_name>" to the end of the original file's path.
Example: /content/dam/mysite/images/image_001.jpg/jcr:content/renditions/cq5dam.thumbnail.48.48.png
My question is, does the jcr part (the bolded part in the example), except for the file size and extension, always the same for thumbnails of any uploaded image files? Where can I find the rules for generating the thumbnail names?
