Best way to set minimap background texture

[lentinant]

I'm trying to implement minimap for my TD, and there is one question for it. I want to set its background with real minimap image (like in most RTS), which will be different for every map. So, i can render level from Top-Down view, and make some fixes in image editor to get proper texture, but i don't know, what's best way to implement different images for one Flash movie. I can set it via frames, and just use "GotoAndStop", but it's kinda... rough.

You can use SetExternalTexture or use the UILoader.
