AI2 supports basic GIF format, however it
does not support
animated GIFs. Users can simulate the 'movie' effect of an animated gif using multiple images instead. Some picture manipulation software may allow you to separate the individual 'frames' of an animated GIF. You can use them and cycle through them if you want to expend tht much effort.
Sorry, animated gifs do not respond in AI2; multiple images is an imperfect work-around.
