I was attempting to post this art made by luckyluckyluckypenny: www.furaffinity.net/view/24942204/ but when uploading it I get an error it already exists, going to the link provided for where it supposedly already exists just sends me to the first page of posts. And combing through luckyluckyluckypenny's posts didn't reveal it to be there. Any help?

That means the image was uploaded before and was later deleted.
