Here's my script...

if it is "Enlarge" then
    lock screen
    go stack "Picture"
    put 300 into theTargetSize -- adjust size here
    set the filename of img "Palette Picture Graphic" to the pictPath of me
    put theTargetSize/the formattedwidth of img "Palette Picture Graphic"
into theRatio
    set the width of img "Palette Picture Graphic" to theTargetSize
    set the height of img "Palette Picture Graphic" to \
        round(the formattedheight of img "Palette Picture Graphic" *
theRatio)
        set the topleft of img "Palette Picture Graphic" to 0,0
    get the rect of img "Palette Picture Graphic" of card 1 of stack
"Picture"
    set the rect of card 1 of stack "Picture" to it
    set the topleft of stack "Picture" to 380,310
    palette stack "Picture"
  end if


Almost there. You can't set the rect of a card. You have to set its 
width and its height separately. Instead of the line "set the rect of 
card 1..." you need to script as follows (watch for line wrap):

  lock screen
  go stack "Picture"
  put 300 into theTargetSize -- adjust size here
  set the filename of img "Palette Picture Graphic" to the pictPath of me
  put theTargetSize/the formattedwidth of img "Palette Picture Graphic" 
into theRatio
  set the width of img "Palette Picture Graphic" to theTargetSize
  set the height of img "Palette Picture Graphic" to \
      round(the formattedheight of img "Palette Picture Graphic" * 
theRatio)
  -- changes to script start here:
  set the width of cd 1 to the width of img "Palette Picture Graphic"
  set the height of cd 1 to the height of img "Palette Picture Graphic"
  set the topleft of img "Palette Picture Graphic" to 0,0
  set the topleft of stack "Picture" to 380,310
  palette stack "Picture"
