Create Image query

I'm curious how you can put a CreateImage in a type without
making the CreateImage Global. Should I merely put the image in a bank, then PeekInt for it when I require it in
the type.
For Example:

Graphics 640,480
gamebank=CreateBank(12)
PokeInt gamebank,0,Rect(MouseX,MouseY,50,100,1)=bat=CreateImage(50,100,0)
PokeInt gamebank,4,Oval(ball\x,ball\y,20,20,0)=ball=CreateImage(20,20,0)
PokeInt gamebank,8,Rect(enemy\x,enemy\y,50,100,0)=bat2=CreateImage(50,100,0)
;Types
Type Player
	Field x,y,bat
End Type
bat1=New Player
bat1\x=MouseX
bat1\y=MouseY
bat1\bat=PeekInt(gamebank,0)
Type Enemy
	Field x,y,bat2
End Type
antagonist=New Enemy
antagonist\x=500
antagonist\y=240
antagonist\bat2=PeekInt(gamebank,4)
Type ball
	Field x,y,ball
End Type
bally=New ball
bally\x=320
bally\y=240
bally\ball=PeekInt(gamebank,8)

Did I do this right?

Yes, I believe this should work, however, not in this context. But using a bank like this should be possible.
An alternative would be making a Type called Image, and destroy it after using it.

What d'you mean? You mean for example, create the
image inside the type?

Yes, however it is just another way of doing the same.
So you can use a type to store the images until you've created all players/enemies etc. After that, this type can be released.
But it doesn't really matter which method you choose, I suppose. The bank thing should work the same.
The advantage of using Banks is that they can be passed as a parameter to the function. Then again, with Types, the functions don't need a parameter, because you can find the images with First/Last/Before/After/For Each from within the function.
