convert bitmap to image c#
<p>this is how my code look now:</p>

<pre><code>System.Drawing.Image objImage = System.Drawing.Image.FromFile(Server.MapPath("aaa.jpg"));

int height = objImage.Height;
int width = objImage.Width;

System.Drawing.Bitmap bitmapimage = new System.Drawing.Bitmap(objImage, width, height);
System.Drawing.Graphics g = System.Drawing.Graphics.FromImage(bitmapimage);
System.Drawing.Image bitmap2 = (System.Drawing.Image)Bitmap.FromFile(Server.MapPath("sem.png"));

g.DrawImage(bitmap2, (objImage.Width - bitmap2.Width) / 2, (objImage.Height - bitmap2.Height) / 2);

MemoryStream stream = new MemoryStream();     
bitmapimage.Save(stream, ImageFormat.Jpeg);

String saveImagePath = Server.MapPath("ImagesMerge/") + "aaa.jpg";
bitmapimage.Save(saveImagePath);
imgBig.ImageUrl = saveImagePath;
</code></pre>

<p>The problem I have now is  that the image is not displayed in browser, I don't understand why .</p>
