How to upload and resizing image in asp.net?

Here is the code:
protected void btnUpload_Click(object sender, EventArgs e)
{
if (flUpImage.HasFile)
{
picName = flUpImage.FileName;
string SavePath = Server.MapPath("~/Coach/Data/" + Convert.ToString(iPlayConstant._PLAYER_ID) + "/");
DirectoryInfo di = new DirectoryInfo(SavePath);
if (!di.Exists)
{
di.Create();
SetPermissions(SavePath);
}
string LocalPath = Server.MapPath("~/Coach/Data/" + Convert.ToString(iPlayConstant._PLAYER_ID) + "/Profile.gif");
flUpImage.SaveAs(LocalPath);
System.Drawing.Image imgSaved = System.Drawing.Image.FromFile(LocalPath);
System.Drawing.Image imgCroped;
imgCroped = ImageResize(imgSaved, 250, 250);//pass the height and width value to create thumbnail picture
imgProfile.Width = imgCroped.Width;
imgProfile.Height = imgCroped.Height;
imgSaved.Dispose();
imgCroped.Save(LocalPath);
imgCroped.Dispose();
imgProfile.Src = "~/Coach/Data/" + Convert.ToString(iPlayConstant._PLAYER_ID) + "/Profile.gif";
}
}


protected static System.Drawing.Image ImageResize(
System.Drawing.Image imgPhoto, int dWidth, int dHeight)
{
int sourceWidth = imgPhoto.Width;
int sourceHeight = imgPhoto.Height;
int destWidth = dWidth;
int destHeight = dHeight;
int sourceX = 0;
int sourceY = 0;
int destX = 0;
int destY = 0;
float percent = 0;

if (sourceHeight > sourceWidth)
{
percent = (float)sourceWidth / (float)sourceHeight;
destWidth = (int)(percent * destWidth);
}
else
{
percent = (float)sourceHeight / (float)sourceWidth;
destHeight = (int)(percent * destHeight);
}
if (destWidth > destHeight)
{
percent = (float)sourceHeight / (float)sourceWidth;
destWidth = (int)(percent * destWidth);
}
System.Drawing.Bitmap bmPhoto = new Bitmap(destWidth, destHeight, PixelFormat.Format24bppRgb);
bmPhoto.SetResolution(imgPhoto.HorizontalResolution, imgPhoto.VerticalResolution);
Graphics grPhoto = Graphics.FromImage(bmPhoto);
grPhoto.InterpolationMode = System.Drawing.Drawing2D.InterpolationMode.HighQualityBicubic;
grPhoto.DrawImage(imgPhoto,
new Rectangle(destX, destY, destWidth, destHeight),
new Rectangle(sourceX, sourceY, sourceWidth, sourceHeight),
GraphicsUnit.Pixel);
grPhoto.Dispose();
return bmPhoto;
}
