Image layers

[Yen]

I have an NPC and a showimg.
The NPC's layer is 0.
The showimg is just below the center of the NPC.
The problem is that I want to show the showimg above the NPC, but below the player. If I set the showimg's layer to 0, it goes below the NPC. If I set the showimg's layer to 1, it goes above the player.

Is there any way around this?
