I want to have an image scroll up the screen at a slow rate a thik you have to change the y coridants but I'm not quite sure how to get it goind up slowly

I got this but it's a bit jerky

Graphics 800,600

scroll=LoadImage("scrolling text.jpg")

l#=600

Repeat

DrawBlock scroll,0,l#
Cls 
l#=l#-1
Delay 10
Until l#=-100

I don't thinks thats how it's ment to be done
