Demo option for graphicx in memoir?

Question

How can I activate the demo option for the graphicx package when using memoir? Is there an equivalent option in memoir?

When I try:

\usepackage[demo]{graphicx}

I get:

! LaTeX Error: Option clash for package graphicx

Update (solved)

Memoir does not load graphicx, so the solution is to add \usepackage[demo]{graphicx} before any other package loads graphicx, as @egreg pointed out in the comments.

Answer 1

As the comments point out, I can just add \usepackage[demo]{graphicx} in the preamble. The option clash has nothing to do with memoir.

I am loading other packages in the preamble which is why I believe I had the option clash. The problem was resolved when I added \usepackage[demo]{graphicx} at the beginning of the preamble (before any other packages were added).

As a reference, I was adding these packages in the preamble:

mathpazo
tikz
ragged2e
fontenc
listings
hyperref
geometry

Answer 2

One solution that does not depend on the load order of the packages is to add demo as an option to the document class:

\documentclass[demo]{memoir}

\usepackage{mathpazo}
\usepackage{tikz}
\usepackage{ragged2e}
\usepackage{fontenc}
\usepackage{listings}
\usepackage{hyperref}
\usepackage{geometry}
\usepackage{graphicx}
