TShowImg with layer 3

[FireHunter]

Well im stuck at a script:
I've made 2 TShowImg in the Tile-Light-Layer ( 3 ) on the same position
(Background Img + Text)
Well both stay in at least the Layer 3 or a few other npcs with drawoverplayer(); will hide the background image
now my problem is that the Background image is always on the top hiding the Text under it - is there a posibility to bring the text into the front ?
(Both must stay on the Tile Layer + on top of every other Image)
