Hi there,
Do you have the .blend file for this?

Cheers

It looks like you just have an object named "PIC" in the scene tree. Is that the only reference the script needs to find the texture and replace it? This script is hugely helpful, thanks so much for posting this.

Can you please tell me how the texture file (2012720989_c.jpg) looks like?
