Hi,
I have the following code which animates a sprite.I wanted to add a background using LoadImage but it continually flickers.Any suggestions why 'image' flickers ? Thanks in advance.

[/code]
Graphics 800,600 'set gfx mode
Global FrameTimer = MilliSecs()
Global frame:Int = 0
Global x:Int =0
Global myimage:TImage = LoadAnimImage("ko1.png",32,32,0,240)
Local image:TImage=LoadImage("pitch.png",flags=-1)
DrawImage image:TImage,0,0,frame
Flip
sound=LoadSound("bouncy.ogg")
PlaySound sound
Repeat
'Cls
DrawImage myimage,x,50,frame

If MilliSecs() > FrameTimer + 100
FrameTimer = MilliSecs()
frame:+1
EndIf

If frame >239 Then frame = 0

Flip
FlushMem

Until KeyHit(KEY_ESCAPE)
soundover = LoadSound ("gameover.ogg")
PlaySound soundover[/code]
