For example we have this piece of the datablock:
datablock ShapeBaseImageData(PoisonStatusPlayerImage)
In this case, the "PoisonStatusPlayerImage" is the name of this datablock.
Be sure to replace references to that specific name to our new name.
(Search and replace!)
And give them logical names.
Names like ololnewdatablockname1 and ololnewdatablockname2, aren't gonna help you in the long run.
