Hi,
You can add an image from an URL via
TMSFNCBitmapContainer1.AddFromURL('http://localhost:8888/Project42/1.jpg', 'MyImage');
And then afterwards use the following code to paint the image
TMSFNCPDFLib1.BeginDocument('test.pdf');
TMSFNCPDFLib1.BitmapContainer := TMSFNCBitmapContainer1;
TMSFNCPDFLib1.NewPage;
TMSFNCPDFLib1.Graphics.DrawImageWithName('MyImage', PointF(100, 100));
TMSFNCPDFLib1.EndDocument(True);
