Does this image need attribution or is this something you created?

[Sembauke]

What do you mean by "attribution" ?

I am not sure, it is used in The Odin Project. But I don't think that's enough of a reason:

Its a CC-BY-SA-4.0 CC BY-NC-SA 4.0, https://www.theodinproject.com/terms_of_use - you will need to add an attribution to the odin project (where the images is) as a caption, and mention that its a CC-BY-SA-4.0 CC BY-NC-SA 4.0

OR

Figure out not needing to the images.

Edit: Its CC BY-NC-SA 4.0

Is this not enough? It's approved by The Odin team themselves. Adding anything to the image itself is absolute overkill.
