Loading Image from "google maps static map" URL

Hi,

I'm trying to load a google maps static map image to my windows mobile 6 prof. application. Those kind of images don't have extension, only URL (i.e. "http://maps.google.com/staticmap?center=45.728220,4.830321&zoom=8&size=200x200&maptype=roadmap&key=ABQIAAAAaHAby4XeLCIadFkAUW4vmRSkJGe9mG57rOapogjk9M-sm4TzXxR2I7bi2Qkj-opZe16CdmDs7_dNrQ")

I have been doing a lot of research about this, but I haven't found any code. I have read that StreamReader should be used  but I don't know how to do it, neither how to set my pictureBox to post the downloaded Image. I'm working in c#.

Can anyone help me here please?

Thanks in advance,

José Domingues
