Seems to happen with a file processing function? ~ is a special notation for the root of the web application which is never used "as is":
here it seems you want to use first Server.MapPath("~/output000.jpg") to convert that "virtual path" to a physical path such as "C:\inetpub\vs2012\EditSelfIntro4\output000.jpg"
else it is converted to a url such as "https://mysite.com/output000.jpg"
It allows to write code without having to know where your site will be installed but it needs to be converted to a physical path or an url before being used.

PatriceSc has guessed that this was your code and shown the correct way to get the filename.
