Based on Chris's explanation about the 504 responses (data serialization), 
I don't think those would affect the image in any way, since it is not 
responding during the operation.
I think it would be worth to add delays. I usually use exponential 
backoff with an upper limit (e.g. 10 seconds).

Maybe. 4xx reponses normally mean the client is doing something wrong. 5xx 
reponses mean there's something wrong with the server.
