title: How to load a bmp without background
body: <p>So, I was trying to make game in allegro but I'm currently stuck with this damn blank background which is making me very mad, as I know PNG images have transparency in the background already, but I can't load pngs, i have already download devpaks, installed libraries and stilll nothing good happened, if the best option for me is to use PNG so please tell me how to load then and use then correctly.</p>
  
  <p>If the best option is still to use BMP and there is a algorithm, function or a little code which will make the blank background go away please tell me.</p>
  
  <p>For those who didn't understand what I want there is a better explanation:

  <p>its currently in .png, but I transformed to .bmp in paint, so it makes me a blank background and in allegro it shows the whole picture, i want to have only the ball.</p>
