je copie colle de ma vieille msdn locale :
LoadImage
The LoadImage function loads an icon, cursor, or bitmap.
HANDLE LoadImage(
HINSTANCE hinst, // handle of the instance containing the image
LPCTSTR lpszName, // name or identifier of image
UINT uType, // type of image
int cxDesired, // desired width
int cyDesired, // desired height
UINT fuLoad // load flags
);
y'a aussi BITMAPFILEHEADER, BITMAPINFOHEADER, etc ...
