Image in pop-up window

[Shao Sean]

on mouseUp
  local vTempWindowID
  lock screen
  if ("picturePalette" is among the lines of the openStacks) then
    clone stack "picturePalette"
    put it into vTempWindowID
    set the title of vTempWindowID to "Viewing Picture:" && the short name
of me
  else
    go invisible to stack "picturePalette" in a new window
    set the title of stack "picturePalette" to "Viewing Picture:" && the
short name of me
    show stack "picturePalette"
  end if
  unlock screen
end mouseUp

you may also want to look at putting it into a function and having the
buttons call the function passing their short name as a parameter..

this code may or may not work 100% with copy-paste, so give it a test and
you may need to tweak it a little..
