  Hi Flippy,

  1.
  the easiest way is to define buttons (e.g. the number buttons).
  In your case i would implement something in the images "press 'n' for no" or "press 'x' for yes".

  If you want to do it with mouse presses you need to define the position of the response fields. Quite more complicated.

  2.
  Why don't you put your 4 images into one image if they shall be presented at the same time?
  So you need to present only one canvas.
  Another option would be to present the images one after the other. Which seems more logical to me, but i do not know your experiment.

  Hi Flippy,

  Here a code with mouse clicks. This code works with two Items on one page. You need to find the rectangles (x,y coordinates) of your canvas on your own

  StrengthOfRep = canvas()
  StrengthOfRep.image(pool['StrengthOfRep.tif'])
  
  list_x = [-378,-291,-204,-117,- 28, 60,147,234,321]
  kin_list = []
  
  for i in range(9):
      StrengthOfRep[i] = Rect(x=list_x[i], y=-57, w=59, h=59, color='white', penwidth=1)
      kin_list.append(StrengthOfRep[i])
  
  vis_list = []
  for i in range(9):
      StrengthOfRep[i+10] = Rect(x=list_x[i], y=181, w=59, h=59, color='white', penwidth=1)
      vis_list.append(StrengthOfRep[i+10])
  
  var.vis=None
  var.kin=None
  #def StrOfRep():
  StrengthOfRep.show()
  my_mouse = Mouse(visible=True)
  
  while (var.kin==None or var.vis==None):
      button, (x, y), time = my_mouse.get_click()
      for i in range(9):
          if (x, y) in kin_list[i]:
              var.Stim='kin'
              var.Resp=i+1
              var.kin=True
              for ii in range(9): #set all others white
                  kin_list[ii].penwidth = 1
                  kin_list[ii].color = 'white'    
              #mark the selected one
              kin_list[i].penwidth = 4
              kin_list[i].color = 'blue'
              log.write_vars()
              StrengthOfRep.show()
          elif (x, y) in vis_list[i]:
              var.Stim='vis'
              var.Resp=i+1
              var.vis=True
              for ii in range(9): #set all others white
                  vis_list[ii].penwidth = 1
                  vis_list[ii].color = 'white'    
              #mark the selected one
              vis_list[i].penwidth = 4
              vis_list[i].color = 'blue'
              log.write_vars()
              StrengthOfRep.show()
