Unfortunately (as I'm sure many have discovered and I am currently  
discovering), there's no "best" way to do something like this.  You  
could set a variable and draw one or the other image based on that  
variable's value (meaning one more if() statement each frame), or you  
could set some pointer variable to a drawing structure to point to a  
different image each time it needs to switch...  Those are the only  
two reasonable ones I can come up with.  The others a far more  
obscure and unlikely.

Do either of those help at all?

I think a lot of "best" depends on how you're structuring your  
entities, also.
