try this:

System.usbDiskModeActivate()

green=Color.new(0,255,0)
orange=Color.new(255,128, 0)
teal=Color.new(64,128,128 )
blue=Color.new(0,0,255)
red=Color.new(255,0,0)
black=Color.new(0,0,0)
lightgreen=Color.new(18,6 1,36)
lightyellow=Color.new(165 ,157,67)

textX = 300
textY = 100
textColor=blue

background = Image.load("pic/background.png") --make sure this is the correct path

while true do
screen:clear()
pad=Controls.read()
if pad:cross() then textColor=green
elseif pad:triangle() then textColor=orange
elseif pad:circle() then textColor=blue
elseif pad:square() then textColor=red
elseif pad:start() then textColor=teal
elseif pad:l() then textColor=lightgreen
elseif pad:r() then textColor=lightyellow
end

if pad:up() then textY=textY-5
elseif pad:down() then textY=textY+5
elseif pad:left() then textX=textX-5
elseif pad:right() then textX=textX+5
end
screen:blit(0, 0, background, 0, 0, background:width(), background:height(), false)
screen:print(textX, textY, "hello people here!",textColor)
screen.waitVblankStart()
screen.flip()
end

Image.load() only loads the image into VRAM, you need to then blit the image to screen.

thanks a ton that really helps but now 2 questions one what does blit the line blit tell the psp with all the 00's and everything that well really help me so i know what i am doing and how do i make it to take up the whole screen not just a portian

thanks

nil image:blit(x, y, Image source, [sourcex, sourcey, width, height], [alpha = true])

If you want the image to take up the whole screen, just make it 480x272.
