Infinite keyframes help[MX]

I was wonder if this was possible…Im new to action script so this question might sound dumb…
Is there a action script code that will allow me make something in the key frame show through the whole movie…

For example
3RD frame I want a jpg image to show till the end of the movie…
The movie is 500 frames…
Can I put a code on the 3rd frame to tell it to show itself all the way to the end of the 500 frames…instead of clicking on the 500 frame and placing a key frame on it?

I looked around the forums and on google…found nothing on it…please help:hangover:

you gotta divide the modem speed by 8 to get the kb/s value, so 56 by 8 makes seven.
taking this into consideration, 25k need nearly 4 seconds to load on a normal modem which can already annoy some users…

That is true…I remember when I had a 56k…something that was 25 kb didnt take a second…(i wish)…not only that…there is no 56k that actually performs at 56kbs…top speed i heard on a 56k was 40kbs…i remember my high was 35kbs…D*mn you AOL!
My teacher told me a website site for people on 56ks shouldnt be higher then 50kbs…if it is…studies have shown that you lose about 70% of the viewers…(people dont like waiting)
So size does matter…and when you want to make a site thats suitable for everyone not just high speed users…then 25kbs is something that can make a difference.
