public class JPEGHTTPClient

extends AbstractJPEGStream

HTTP client subclass to AbstractJPEGStream. Simply passes on any request for an image to a specified HTTP server.

Doesn't know much about the size of the images the server sends. For now, this client just assumes some standard size. Also, this class has no idea of when an image was actually taken, so the timestamp is simply set to the time the image was received over the network.
