Hello there, had a quick question on how to do LOTS of little graphics optimaly.

My graphic is leaves, its a ground cover for a forest scene, and currently i have a .GIF of a small pile of leaves that i have imported to flash and put into a graphic, and i copy/paste it 100 times to cover the entire screen. Is this the most optimal way of doing it? Or is one large .GIF better?

Thats, was curious =)
