[RM2K3] HOW TO MAKE A PICTURE SCROLL WITH A MAP?

I've got an issue with the show picture command currently. I've gotten a picture of text to appear on the screen, and set it to scroll with the map, however whenever 50% of it goes off screen it jumps back to the centre. I want this text/image to follow the scroll all the way off map and out of sight. Any ideas?

I've fixed it, no need to worry! :D
