I was just looking through your index:

The file: e2a20d4eec491b9a00ed79818b2d94a2.png doesn't exist so that's why it's not finding it.
Edit: You may have removed it since that post and it did exist.
I've noticed the script needs to be installed in the exact same place in order to keep the right file location.
