You can have an array of images. Try a Timer to make the frames appear in turn. You can have an index and use the remainder operator to bring it back to the beginning of the array.
Don't make the timer fire more frequently than about once per 20ms or once per 25ms. Your four‑element array would move far too fast at that speed. You can try about once every 100ms, but I think your animation will be horribly jerky. Is there any way you can interpose more frames and make the motion smoother?

No matter. Try again. Fail again. Fail better. This time, do it with this tiny ad:
