To change the pointer image you will make the player spend lots of CPU because the program will use the method/event:on mouseWithin in the sprite script trigger and the mouse is always over the world (that is the sprite).

We will use the trick of the ray of the modelsUnderLoc method (the same used to capture clicks).

The trigger script now has two methods:

global avatarobj

on mouseWithin me --to  capture the mouseover
  cursor(-1) -- the normal image

  set0=point(sprite(1).left,sprite(1).top)
  pt0 = the mouseLoc - set0
  m0 = sprite(1).camera.modelsUnderLoc(pt0, 3, #detailed)
  if m0.count>1 then
   if  m0[1].model.name ="pic"  OR  m0[2].model.name ="pic"  then
    cursor (280) -- the "finger" image
   end if
  end if

end

on mouseUp me --to capture the click 
 set=point(sprite(1).left,sprite(1).top)
  pt = the mouseLoc - set

  m = sprite(1).camera.modelsUnderLoc(pt, 3, #detailed)
  if m.count>1 then
   if  m[1].model.name ="pic"  OR  m[2].model.name ="pic" then
    avatarobj.link=1 
   end if
  end if

end

    0     No cursor set
 
   -1     Arrow (pointer) cursor
 
    1     I-beam cursor
 
    2     Crosshair cursor
 
    3     Crossbar cursor
 
    200   Blank cursor (hides cursor)

You can create a new image. We will have a lesson about this in the future.

Play the demo (again) going inside the building (the gallery), looking the "painting" and puting the cursor over it. Perhaps there are a bug - mine? - and the change-of-cursor only works until you go to the linked page. Is it a genial solution to not spend CPU? Sometimes nothing works :-(
