I am trying to resize an image in a folder. The code I am using is this:

```
string logoUrl = HttpContext.Current.Server.MapPath("DeviceLogo");
System.Drawing.Image SourceLogo = System.Drawing.Image.FromFile(logoUrl + @"\" + objDevice.FileName);

//Create a logo for this device and reseller/client business              
Bitmap newImage = new Bitmap(objDevice.LogoWidth, objDevice.LogoHeight, PixelFormat.Format24bppRgb);
using (Graphics graphics = Graphics.FromImage(newImage))
{
    graphics.CompositingQuality = CompositingQuality.HighQuality;
    graphics.InterpolationMode = InterpolationMode.HighQualityBicubic;
    graphics.SmoothingMode = SmoothingMode.HighQuality;
    graphics.DrawImage(SourceLogo, 0, 0, objDevice.LogoWidth, objDevice.LogoHeight);
}
string filepath = HttpContext.Current.Server.MapPath("DeviceLogo");                

//Save the resized image                
newImage.Save(filepath + objDevice.FileName);

```

The problem is that the image is not getting resized
