Try this for resizing and save to a new location

string strPath = @"D:\MemberImage\MyPhoto.jpg";
            System.Drawing.Image img = System.Drawing.Image.FromFile(strPath);
            img=Resize(img, 160, 120);
//resize image 
private Image Resize(Image img, int iWidth, int iHeight)
            Bitmap bmp = new Bitmap(iWidth, iHeight);
            Graphics graphic = Graphics.FromImage((Image)bmp);
            graphic.DrawImage(img, 0, 0, iWidth, iHeight);
            return (Image)bmp;

try the following :
string directory = AppDomain.CurrentDomain.BaseDirectory + "PhotoGallery/Slides/";
Bitmap originalBMP = new Bitmap(fuphotos.FileContent);

int origWidth = originalBMP.Width;
int origHeight = originalBMP.Height;
int sngRatio = origWidth / origHeight;
int newWidth = 213;
int newHeight = 200;

Bitmap newBMP = new Bitmap(originalBMP, newWidth, newHeight);

Graphics oGraphics = Graphics.FromImage(newBMP);
oGraphics.SmoothingMode = SmoothingMode.AntiAlias; oGraphics.InterpolationMode = InterpolationMode.HighQualityBicubic;

oGraphics.DrawImage(originalBMP, 0, 0, newWidth, newHeight);
newBMP.Save(directory + cfilename);


strcFilepath = @"~/PhotoGallery/Slides/" + cfilename;

Why, with extension methods, of course:

public static class ExtendBitmap
    public static Bitmap Resize(this Bitmap bmp, int nWidth, int nHeight )
        Bitmap result = new Bitmap(nWidth, nHeight);
        using(Graphics g = Graphics.FromImage((Image)result))
            g.DrawImage(bmp, 0, 0, nWidth, nHeight);
        return result;
    public static Bitmap Resize(this Bitmap bmp, double percent)
        int width = (int)(bmp.Width * (percent*0.01));
        int height = (int)(bmp.Height * (percent*0.01));
        Bitmap result = bmp.Resize(width, height);
        return result;

Load the bitmapo the way you normally would, and then do this:

Bitmap bmp = Bitmap.FromFile("blah blah");
bmp = bmp.Resize(50);
// or 
bmp = bmp.Resize(320, 240);

Whatever you do. You are going to loose transparency, it will be replaced with black color.

Any solution for bitmaps ?
