One way to do this is to USE the IImage interface and SET the rate of animation (IImage_SetParm).

An example in which the animation rate is set to 750ms is shown below:

IIMAGE_SetParm(pMe->m_pIImage, IPARM_RATE, 750, 0);

You can also use a timer to trigger the IMAGE display FUNCTION. Use ISHELL_SetTimer() to set a timer:

ISHELL_SetTimer(pMe->a.m_pIShell, TIMER_RATE, (PFNNOTIFY)(ManipulateBitmap), pMe);

After TIMER_RATE ms expires, ManipulateBitmap function will be triggered, within which you can manipulate your image.
