With the new upscale x2 and x4, we receive progress updates but the attachments list is empty, so there is no image progress sent to the client. These upscales are very slow so it creates a long delay without any progress and can cause problems to client applications.
With this small patch, if the user configures UpdateProgressWithoutImage to "true", these updates will be sent with the "EmptyImageUri" from the config ( defaults to "about:blank" ).
By default behavior is the same as before.
