In order to load image from file in C#, you can load them as following way. The image type could be Jpeg, GIF, Bitmap(BMP), as well as PNG.
Image m_source = Image.FromFile( 'the file name you need to load');
Isn't it simple ?

Here's how to draw tiled bitmap image on a Form:
type
TForm1 = class(TForm)
procedure FormCreate(Sender: TObject) ;
procedure FormPaint(Sender: TObject) ;
procedure FormClose(Sender: TObject;
var Action: TCloseAction) ;
private
public
end;
var
Form1: TForm1;
Bitmap: TBitmap;
...
procedure TForm1.FormCreate(Sender: TObject) ;
begin
Bitmap := TBitmap.Create;
Bitmap.LoadFromFile('C:\WINDOWS\cars.BMP') ;
end;
procedure TForm1.FormClose
(Sender: TObject; var Action: TCloseAction) ;
begin
Bitmap.Free;
end;
procedure TForm1.FormPaint(Sender: TObject) ;
var
X, Y, W, H: LongInt;
begin
with Bitmap do begin
W := Width;
H := Height;
end;
Y := 0;
while Y < Height do begin
X := 0;
while X < Width do begin
Canvas.Draw(X, Y, Bitmap) ;
Inc(X, W) ;
end;
Inc(Y, H) ;
end;
end;
TForm1 = class(TForm)
procedure FormCreate(Sender: TObject) ;
procedure FormPaint(Sender: TObject) ;
procedure FormClose(Sender: TObject;
var Action: TCloseAction) ;
private
public
end;
var
Form1: TForm1;
Bitmap: TBitmap;
...
procedure TForm1.FormCreate(Sender: TObject) ;
begin
Bitmap := TBitmap.Create;
Bitmap.LoadFromFile('C:\WINDOWS\cars.BMP') ;
end;
procedure TForm1.FormClose
(Sender: TObject; var Action: TCloseAction) ;
begin
Bitmap.Free;
end;
procedure TForm1.FormPaint(Sender: TObject) ;
var
X, Y, W, H: LongInt;
begin
with Bitmap do begin
W := Width;
H := Height;
end;
Y := 0;
while Y < Height do begin
X := 0;
while X < Width do begin
Canvas.Draw(X, Y, Bitmap) ;
Inc(X, W) ;
end;
Inc(Y, H) ;
end;
