Can't get rotator to work

Can't get rotator to work

Hello Everyone,

I am trying to make a simple image rotator using JQuery. It seems to work for first loop however it does not iterate back to the start of images once it reaches the last image. I have tested and the code is getting the first image reference but due to some reason it is not working. Can anybody kindly help me. I have attached my code.

Best Regards,
