PuppetPin to Null: image jumping

PuppetTool  AE Script:

If your ever wondering why on earth is your image jumping from it's original location after applying the script, well look no further.
It's because you've moved the anchor point: ie the picture, the image is reading the anchor point centre.

So...... hence, do not move your anchor point, leave it as it is imported. Create your pins and apply the script and tadaa!
