loading many images from the web

  did you try to create a list of items to be downloaded and a generic function to download an image, then spawn this function with each of the images.
  
  Apart from that, you will have to explain a bit better on what exactly are you after, because if you are wanting to download all the images from a web page, then you need to parse the source of the page and work on it to create that list of images.

  There are examples of the http load request functions floating around the forum. When I last looked you had to queue up your requests and have a single function that would issue the load and handle the onComplete callback so that the next item in the queue could be loaded.

  local function onComplete(self,event)
  local out = io.open("|T|birdmy.png", "wb")
  out:write(event.data)
  out:close()
  
  local b = Bitmap.new(Texture.new("|T|birdmy.png"))
  self = b
  stage:addChild(self)
  end
  
  function Node:iconConverter()
  load = self.icon
  load:addEventListener(Event.COMPLETE, onComplete,self)
  end

  Hi @tugbakaya,
  
  As @techdojo said, you need to queue your elements and load sequentially. And Event.COMPLETE and Event.ERROR should fetch the next element on the queue.
  
  You can look at the attached simple example.
