You can use an image editor like Corel Photopaint or Adobe to clip out those parts you want to move. Then move those objects on the top of a "blank denarius field" saving each "frame" as a .jpg. Then load all the frames in order and re-save the multiple frames as a gif or the more modern PNG format. It should play automatically when uploaded somewhere or clicked on.
