When images are loaded over a slow connection, there is a white screen till it loads

When images are loaded over a slow connection, there is a white screen till it loads --> on tracing logs it seems that nph-zms sends a blank HTTP 200 OK immediately and then transmits the image. Switching to just zms (as suggested by @knnniggett) alleviates this issue. The next issue to tackle is the delay in loading of the image - if its a large image, it still takes 4-5 seconds at times, depending on network and zms performance

I fixed this issue - figured out a way to intercept image loading. The strategy implemented is as follows - when the modal first loads, I show a loading message (I know the only reason the modal loads is to show the image stream) add a "directive" to img src that traps the image finished loading attribute (cool, did not know that existed). On image load completion, I remove that message so the user is not left with a blank screen wondering what is going on. I've set a timeout to 15 seconds for that message to handle situations where no image comes through from zms (happens some times and no error is reported either)
