what are you using to render them or are you just finding them online?
CoPilot Image renderer which uses DALL-E. I even did a Google Image search after the render and went through more than 100 images without finding that one (there are a zillion galleons online, btw).
If you had found a duplicate, I would have expected you to send a pm, SimplexDesigns.
I have no reason to suspect what you implied as it generated four separate though similar images, and stated it was generating the images per my typed specifications.
When it can't follow instructions and generate my requests, it returns images with their source.
Here are the results of a Tineye image search on my last two uploads for everyone's perusal.
