[Gimp-user] Animated .gif's

[Robert Keane]

Hello All,

This question might piss-off the whole list because it is so basic but I
know nothing about the subject and I don't know where else to post it.
So here goes.

I was given a .gif that I would like to use on a web site. it shows a
pen writing on a piece of paper, the paper being folded, then inserted
into an envelope and the envelope disappearing to the right. The problem
I have with it is that it repeats ad nauseum where once would be just
fine. My question is can I stop the animation after 1 time?  If so, can
I then substitute a folded envelope for the previously animated .gif.

Regards,
Robert Keane
