Re: Looping?
Execution order is largely determined by which nodes don't need data, or have all the data the need. They can run first and provide data downstream for the nodes that need more data values.
In addition, the structures such as the loop or case act as a node on the outside, but do special things to their inner diagram.
What this results in is sequencing automatically when data is present and flowing, and parallelism when it is not.
To your direct question, I think you want to draw a loop around the lower portion of the program, but not the client portion. You don't really need to include the create image, but it doesn't hurt.
