If you have a canvas containing the image, you can change visibility using the show attribute:

canvas_name.show: "none"
canvas_name.show: "solid"

To show or hide it on a delay, there is a simple way and a more complex way.

The simple way uses the sleep function. It (mostly) pauses the whole program until it’s finished sleeping. For example, you could use it in a button’s click action:

# Simple, e.g. button script
on click do
  card.widgets.canvas_name.show: "none"
  sleep[60] # number of frames to sleep for
  card.widgets.canvas_name.show: "solid"
end

Complex uses sys.ms and recursive go[] functions to allow other things to occur in the meanwhile. You’d need a hidden field to store some extra data. Here the image shows after 1s.

# Complex, with a field called hidden_time
# Button script
on click do
  card.widgets.canvas_name.show: "none"
  card.widgets.hidden_time.text: sys.ms
  go[card]
end
# Card script
on view do
  elapsed: sys.ms - card.widgets.hidden_time.text
  if elapsed > 1000
    card.widgets.canvas_name.show: "solid"
  else
    go[card]
  end
end
