I don't know how much you know about actionscript but i've
attached a code that will pause the timeline for 5 seconds on the
frame you put this code, then it will continue on. So you could lay
out all your images with fade in and fade outs then put this code
on the image when you want it to pause for 5 seconds, or you can
change the timing to whatever you want, just change the 5000 which
is for 5 sec to whatever you want like 3000 for 3 sec and so on.
You could put this all in a movie clip if you wanted it to loop
endlessly or you could just have it run through once, by ending
with a stop( ); on your last frame. I hope this helps!! Good luck!
