could someone move this to the lua help thread ?
and btw, you could also try posting your piece of code first, then I'm sure someone would take a look at it and tell you what you're doing wrong
also, I remember posting a download function for lua here somewhere, just search for it

EDIT: here's the download function

[Nielkie]

I'm not usually the one to hand out code, but I was bored.
For PGE Lua:

SERVER = "example.com"
MAX = 10


downloadedImages = {} --Why delete downloaded images?

function downloadAndDisplay(imageNumber)
	local filename = string.format("%03d.jpg", imageNumber)
	if not downloadedImages[imageNumber] then
		local url = string.format("http://%s/%s", SERVER, filename)
		pge.net.getfile(url, filename)
		downloadedImages[imageNumber] = true
	end
	
	local texture = pge.texture.load(filename)
	
	pge.gfx.startdrawing()
	pge.texture.draweasy(texture, 0, 0)
	pge.gfx.enddrawing()
	pge.gfx.swapbuffers()
	
	--texture /should/ be freed by the garbage collector, it might not be.
end


function main()
	local currentImageNumber = 1
	
	assert(pge.net.init())
	
	while true do
		pge.controls.update()
		
		local load = false
		if pge.controls.pressed(PGE_CTRL_LEFT) then
			currentImageNumber = currentImageNumber - 1
			load = true
		elseif pge.controls.pressed(PGE_CTRL_RIGHT) then
			currentImageNumber = currentImageNumber + 1
			load = true
		end
		
		if load then
			if currentImageNumber < 1 then
				currentImageNumber = 1
			elseif currentImageNumber > MAX then
				currentImageNumber = MAX
			end
			
			downloadAndDisplay(currentImageNumber)
			collectgarbage()
		end
	end	
end

main()
