Some thoughts: You could serve images from Cloud Datastore instead of from App Engine. You mention that bandwidth costs dominate instance time, but it should help a bit. If my math is correct, you're serving at least 250GB per day, so provided you're serving mostly to the US, the you'd get some volume discount now <https://cloud.google.com/pricing/#cloud-stor> and then a 33% discount once you top 10TB per month. If nothing else this would help you scale better.
You mentioned the images are served statically. If that's the case, can you crank up the expiration? What are you seeing which makes you suspect that your clients aren't cacheing properly? If your images periodically change can you just generate new filenames in conjunction with effectively infinite expiration time?
