Load and Save Image

Hello, how can I load an image on another server and save it onto my server?  I tried the code below but fromfile doesnt accept URIs as a property.  Should I use httpwebrequest?  How can this be done?

        Dim originalImage As System.Drawing.Image
        originalImage = System.Drawing.Image.FromFile("http://domain.com/images/logo.jpg")
        originalImage.Save(...)

Thanks Very Much!
