LIGHT OVERLAY - CREDIT

Hi all!

First time poster here.
I hope this is the correct section to post this.

In my game I have been using this image:
light5

I am at the stage where I am creating the credits for my game and I am not sure who created this image.
I'm hoping that somebody here will recognise it and be able to inform me of its original creator.

I first came across it here. If that is any help.

I thought about messaging the poster there but I really didn't want to create another account just for that.

Thank you to anyone who can help me.
