### Example
```python
# Attach a photo captured from a camera/upload component to a procedure step check
procedureStepCheckId = 4218
imageName = "torque-check-photo.jpg"
imageType = "image/jpeg"
imageDescription = "Torque wrench reading after tightening bolt pattern"

# byte arrays typically come from a component such as a File Upload or Camera binding
imageBytes = event.source.parent.getComponent('CameraCapture').primaryImage
thumbnail = event.source.parent.getComponent('CameraCapture').thumbnailImage

userId = system.kanoa.security.getIDPUserId({'userName': 'SYSTEM'})
imageId, msg = system.kanoa.cmms.addImage(procedureStepCheckId, imageName, imageType, imageDescription, imageBytes, thumbnail, userId)
print imageId, msg
```
