  Hi Helen,

  I suggest you draw your images directly to a canvas in an inline_script. It's not much more difficult than using a sketchpad, but gives you more freedom and control over it.
  I give you an example of the basic idea. Probably, you'll have to try a bit, until it looks just like you want it to. If you get lost, you can have a look on the documentation page (this is also where I copied most of the code from) or ask again here in the forum.

  Here the example:

  from openexp.canvas import canvas
  from openexp.keyboard import keyboard
  
  
  my_canvas = canvas(exp)
  
  my_canvas.image(file_path_left)
  my_canvas.image(file_path_right)
  
  
  my_keyboard = keyboard(exp)
  t0 = self.time()
  
  while (self.time() - t0) < 2000:
  
      response, timestamp = my_keyboard.get_key()
      if response == 'key which makes the right image disappear':
           my_canvas.image(file_of_image_with_background_color)
           my_canvas.image(file_path_left)
      my_canvas.show()
  

  Good luck!

  Eduard

  thanks a lot for your answer. My remaining problem is that I would like to take the images from a list in a loop and somehow I cannot find how to do that. Instead, the get_file function will work with a singe picture, not a list of pictures in a loop...

  Hi,

  You're right exp.get_file works only for single files. However, if you have your filenames in a list, you can simply loop over the list, read the current file, do with it whatever you want, and proceed then to the next file.
  Of course this requires that your list contains all filenames. Creating it can be a tiresome thing to do, so you can think about naming your files in a structured way (e.g. file1,file2,file3, ...), so that you only have to loop over the first till the last number of your filepool and can create the filename on the fly (filename = file + current_number)

  Best,

  Eduard
