I am using the following code to insert a picture as background for my file. Here is my code:
\begin{tikzpicture}[remember picture, overlay]
\node[opacity=0.2,inner sep=0pt] at (current page.center)
{\includegraphics[width=\paperwidth,height=\paperheight]{school.png}};
\end{tikzpicture}
But when I run my code, something went wrong. Here's what I got:
How do I get rid of that "Draft" ？ Which part of my code leads to this？
school.png, then no part of the above code leads to it. The document class probably is the reason for this or some other loaded package.
