Maybe because none of those 2300+ viewers has any idea what you are trying to accomplish given your one line description, and probably no one has done anything like this. I certainly haven't.

But it sounds like your solution is too tightly coupled. In generic terms, you want to overlay a tile containing an image on a map. The source of the image shouldn't matter, only that the tile should update when a new image is set on it. So I would suggest finding a way to decouple getting image data from the server from displaying that image in a tile - maybe a class that knows the association between a tile and the image source, and another class that monitors the source for updates, creates a new image, and loads it onto the tile.
