```
int newWidth = 100;
int newHeight = 100;
double ratio = 0;

if (img1.Width > img1.Height)
{
    ratio = img1.Width / img1.Height;
    newHeight = (int)(newHeight / ratio);
}
else
{
    ratio = img1.Height / img1.Width;
    newWidth = (int)(newWidth / ratio);
}

Image bmp1 = img1.GetThumbnailImage(newWidth, newHeight, null, IntPtr.Zero);
bmp1.Save(Server.MapPath("~/Uploads/Photos/Thumbnails/") + photo.PhotoID + ".jpg");

```

I always get Image with both height and width having same values (100)  

I am obiously doing something wrong with type conversion?
