PageMill can support animated GIF files-GIF files that contain a sequence of several image files. When the reader clicks an animated GIF file, it cycles through the images like an old-fashioned flipbook.
Once the animated GIF file is saved, import it into Adobe PageMill just as you would any other GIF image.
To play an animated GIF file, make sure the page is in Preview mode. Double-click the image to start the playback. To stop playback, click once.
An animated GIF can be placed onto your page exactly like any other graphic: by using the Place command, or by dragging it in from the Windows desktop.
