Using the Frames dialog we can select which frames of an animated Gif file we want to import. We can select more than one frame. This dialog is automatically shown when we try to import a Gif file. If the "Over-impose frames" check box is checked, then the frames are over-imposed, and they will be imported as we see it in the Gif file. However if this option is not checked then the frames will be imported as they are stored inside the Gif file.
