I'm not sure it sounds like an issue with the load balancer, as a load
balancer shouldn't have any qualm with passing through the image data
associated with an http request (which is what the fopen wrapper
essentially performs behind the scenes.) It's possible that the prod
servers (those making the call to fopen) aren't configured to allow the
http wrapper. It could just be as simple as allow_url_fopen being set to
false, in contrast to the configuration of the dev server(s).
