Importing Geotiff via grasshopper

I would like to be able (directly from grasshopper) to import a generated geotiff file from the web and save this in a specified folder as TIFF using the following link:,51.531508,5.980004,51.535109&WIDTH=801&HEIGHT=801

If you paste this link in Google Chrome a tiff file will be downloaded and put into the download folder. But this has to be done by hand. For WFS webservices I can use the following C# script: (6.5 KB)

For downloading and saving tiff files probably more is needed. Does anybody knows where I can find information how this could be accomplished.
