  23      Used by live checkboxes (item alias function f_k).
  24      Updates a boolean field in database and sends
  25      back an image file
  26  
  27      Params: live_checkbox[short_id][field_id]=action
  28  
  29      where
  30          short_id is the item short ID
  31          field_id is the field ID (like "highlight......")
  32          action is one of on, off and decides whether the checkbox should be switched on or off
  33          (it looks like action is ignored, and the field is just toggled - mitra)
