As it happens, I’ve just made a new FAQ about setting up to downlaod an image. 
You’ll find it here: Downloading & Animating Images
Follow the instructions in the first section, “DOWNLOAD”, and make sure you have the button in the bottom right hand corner set to “Uploads On”, as it is in the FAQ. 
Then WD will download the image for you, change the name, and upload it again.
If you wanted too, you could just link direct from your page to the satellite image by using code like this where you want the image on your page:
<p><a href="http://www.austrocontrol.at/" target="_blank"><img src="http://www.austrocontrol.at/met_data/satellite/sat.gif" alt="Satellite Image" border="0"></a></p>
