Images can be assigned labels in order to give them context.
These labels can then be used when working with the images via API calls.
NOTE: Labels are assigned via the one2edit™ editor UI.
Select Image
Select the image that you wish to label.
Image Info > Label
Open the Image Info panel to reveal the Label field.
Type the label and press Enter.
The label has now been assigned to that image, as shown in the Structure panel.
Once you have saved your changes to this document, the image will be accessible via this label for API calls.
