Deleting an approved post?

I realized something I uploaded recently has already been uploaded to this website. It got approved too, and I don’t know how to delete it or tell a mod about it. Is there a way I can mark it for deletion? Or a way to delete a post while it’s still pending for future reference?

Thank you

It’s post 4006088 if someone wants to handle it

You can flag images for being a duplicate, if those were already uploaded on the website and have higher quality. Or you post them on the deletion request thread. topic #8984

Remember that you don´t have to flag an image, if it was already on the website, because most of the time the 'reupload' has a higher quality than the original one.
