Much easier to edit the image via script with a pencil.

on mouseUp
  select img 1
  choose pencil
  drag from topLeft of img 1 to botRight of img 1
  choose browse
end mouseUp

This could easily be set up to modify a single pixel in an image..

for instance a button with:

on mouseUp
  changeThisPixel 3,7,"test","red"
end mouseUp

on changeThisPixel pDeltaX,pDeltaY,pImg,pColor
  select img pImg
  choose pencil
  set the penColor to pColor
  put left of img pImg + pDeltaX into tXpixel
  put top of img pImg + pDeltaY into tYpixel
  click at tXpixel,tYpixel
  choose browse
end changeThisPixel

it's instant on my machine
