Decimal place in weather monitor

I have a feeling that the new plugin Yuri is working on based on the Weathermon code will support displaying graphics directly from the web page, but currently it does not. Maybe there's some sort of program that will periodically grab an image off the web and save it locally to the same path/filename. If that's the case, you could set it as a background image for a plugin, but I'm not sure that WM updates the image each time it updates values or not (I'm betting probably not).
