Requirements

  • Image Source Restriction Only images loaded from Chemotion support cloud upload. If the user uploads an image locally (i.e., not from Chemotion), the annotated image cannot be uploaded back to Chemotion.

  • CSRF Token A valid CSRF token must be available. This is handled internally by the system.
