    You should note that GDI/GDI+ (System.Drawing namespace) is not officially supported in ASP.NET – see “Caution” in http://msdn.microsoft.com/en-us/library/system.drawing.aspx.
    WIC is supposed to be used instead GDI+ (see http://weblogs.asp.net/bleroy/archive/2009/12/10/resizing-images-from-the-server-using-wpf-wic-instead-of-gdi.aspx)

    Said that, many had successfully use GDI+ in ASP.NET. Most probably, you should attempt saving image into memory stream (or on file) and then writing saved image into the response. See this link for details: http://www.west-wind.com/weblog/posts/2006/Oct/19/Common-Problems-with-rendering-Bitmaps-into-ASPNET-OutputStream

    Another work-around can be related to user account. Apparently, GDI/GDI+ is bound to device context (screen, printer etc) and they may not be available under service accounts. So you may try running your ASP.NET code on some normal user account if that helps or not.
