How Do I Change an Animated Gif's Iteration and Loop Settings? (Pshop/Image Ready 7.0)

Question

Background to Issue (NOT a PPT or Windows issue even though It will seem like that at first but read on...): I have to make Animated GIFS to be inserted into Powerpoint. I work on a Mac but the PPT presentation will be shown on PCs (non-negotiable, since I can't ask hundreds of sales reps who will be using this to install an outdated version of PPT). I already learned that I need to insert the Gifs while working on a PC or else it won't work). Fair enough- I can put it together on a PC, again not the issue. BUT, when I do THAT, the gifs still wn't animate unless I am in PPT 2002. Fair enough (Microsif going backwards not a surprise) So it won't work in PPT 2003 which is what the users will all have. But I need to get the presentation to them asap! I got a bit further in researching and found out that the solution is that I need to set my "Loop Flag" and "Iteration Settings" appropriately. See this link (http://www.soniacoleman.com/Tutorials/PowerPoint/animated_gifs/gifs.htm)
BUT I am trying to find out if one can do this already somehow in Mac Photoshop 7.0 or Mac Image Ready 7.0, where I made the gif and would prefer to keep making my gifs. Maybe I need to upgrade Image Ready or Pshop to CS? SO THE FINAL QUESTION IS: Is there another way to manual do this without this PC Plug-in?
NOTE: Yes, I know how how to set the loop to "once" or "forever" in Image Ready when I make my Gifs but apparently I need to do this somewhere else...where the iteration setting lives too?

There is an ImageAnimator so you may not need to use byte array instead.
