Create a vertex colored mesh with a picture
The script

import Blender
# ======================
# At least one mesh must be selected
# ======================
MESH=Blender.Object.GetSelected()[0].getData()
# ======================
# We oblige blender to get the bitmap image's colors
# of the texture and/or the lights positionning 1 in the
# 3rd variable of the update. function .
# ======================
MESH.update(0,0,1)
# ======================
# Don't forget to add a material and set the vcol paint
# button
# ======================
