Good day Jeremy,

I hope you are aware of the fact that you create a total of three stacks:
"OriginalStack"
"NewOriginalStack"
"NewOriginalStack-1"

Make sure, the latter two don't get confused...

BTW:
after1ID=afterStacktoIm3ID+2;// 2nd image from stack
should read
after1ID=afterStacktoIm3ID+2;// 1st image from stack

Furthermore, I don't think it is a good idea to compute with image IDs.

Regards

Herbie
