I think Shadd means if the picture isn't online. Like if it's from a camera or MS Paint I once knew, but I forgot how tbh :$
Just a quick note, when it comes to personal pictures - we prefer you to 'attach' them to your post or ideally upload them to your EC gallery. This is because if you link to a picture from say, deviantart, your username may be visible in the URL. Which would be bad for privacy reasons.
