Okay, I hope it was a false positive. If that is the case, would I be okay re-uploading the image in question? And if it happens again and I have not received any notification, either in my messages or e-mail, about why its being removed, then I will likely need an admin here to look into it for me.

When something like this happens and its not a false positive and there is any actual reason for it, I would prefer to know why to avoid any legal issues.
