Loading a texture into a multi frame texture?

Hi,

I have a multi frame texture, i.e.

texture2 = CreateTexure(64,64,12,2) ; 2 frames...

How do I load a texture from disk into say the first frame?
I sort of want to do somehting like...

texture2(0) = LoadTexture("texture2")

This should work. Not sure if the original texture width needs to be 128 ( for 2xframes ) or left at 64.

Hope this helps.

Texture = CreateTexture( 128,64,12,2 )

;assume Tex1 is 64x64
Tex1 = LoadTexture( "Texture1" )
CopyRect 0,0,64,64,0,0,TextureBuffer( Tex1 ), TextureBuffer( Texture )
FreeTexture Tex1
;assume Tex2 is 64x64
Tex2 = LoadTexture( "Texture2" )
CopyRect 0,0,64,64,64,0,TextureBuffer( Tex2 ), TextureBuffer( Texture )
FreeTexture Tex2
