Deleting my pictures?

After reconsideration, the artist and I wanted to pull the pictures I uploaded from the -booru websites. Is there any way that I can go about erasing the images?

The artist must send an e-mail to webmaster@danbooru.donmai.us with the URLs of the infringing posts and proof that they are the artist.

Thank you.

And that only applies to Danbooru, of course.
