Hi
Thanks for the feedback and help. I can confirm that I am the author of this image. The Image has been updated with permissions information and an email request has been sent to permissions-commons@wikimedia.org.
Do you mean different resolution of the same file? If yes, than there is no need for it. You can use this file in other resolutions as well on Wikipedia.
Thanks. I noticed that other people had uploaded different sizes of the same image. Not to worry. I have updated the image to include periodicity. If you could update the file it would be brilliant.
