Lifecycle of Image generation

Image generation follows a life cycle defined by its status:

Status	Status value	Description
Create	0	The generation has been created and will automatically change to the next status "Pending"
Pending	1	The generation has been taken into account and is awaiting processing.
Processing	2	The generation is being processed
Done	3	Generation is complete, and images are available.
Error	4	An error occurred during generation. This may be due to the image description not being accepted. You can modify the generation and try again.
