How to show an image in a field?

[Javier Miranda V.]

on mouseUp
  set the imageSource of char 1 of field "aaa" to  1009
  set the imageSource of char 1 of line 3 of field "aaa" to 1008
  set the imageSource of char 1 of line 5 of field "aaa" to 1011
end mouseUp

Where field "aaa" is the field in whis¡ch the images will be inserted
1009, 1008 and 1011 are the id of the images
