you can use the FacebookMediaObject:

dynamic parameters = new ExpandoObject();
parameters.message = "picture caption...";
parameters.source = new FacebookMediaObject
{
    ContentType = "image/jpeg",
    FileName = Path.GetFileName(Picture_Path)
}.SetValue(File.ReadAllBytes(Picture_Path));

here's the full function to upload a picture to a user or to a facebook fan page: from my blog http://www.codicode.com/art/graph_api_post_pictures_to_a_fac.aspx
