Tikzposter images not displaying

When I compile, the images (.jpg and .png) inserted in my tikzposter document don't display - I just get a box with the image path instead. It looks like this:

Existing answers to similar questions (Why is the picture not inserted?, Images not showing up and Images not visible in PDF) haven't worked for me.

The images did display in this document before, and I can't figure out what I did to stop them showing up.

I've tried commenting out most of the preamble lines individually, but with no success.

Any help would be greatly appreciated.

Here's my MWE:

\documentclass[25pt, a1paper, landscape]{tikzposter}
\usepackage[utf8]{inputenc}
\usepackage{graphicx}

\title{Title}
\author{Name}
\date{\today}
\institute{Institution}

\usepackage{blindtext}
\usepackage{comment}
\usetheme{Basic}

\begin{document}

\maketitle

\begin{columns}

\column{0.33}
\block{Column 1}{

\begin{tikzfigure}[Test\label{here}]
\includegraphics[width=0.33\colwidth]{images/Test.png}
\end{tikzfigure}

}

\end{columns}

\end{document}

• Are you sure you are using this code? It works for me with example-image.png instead of images/Test.png. Sep 15, 2016 at 7:22
• I'm using Sharelatex (www.sharelatex.com). I definitely have this code not producing the image. But - when I copy the code into a new 'project' and try again, it works perfectly. Could it be a problem with some of the other files I have in this project? All I have are the images folder and three .tex files (one for testing pictures and one for snippets of unused code). If not, I guess maybe it's a problem with Sharelatex rather than my code. Sep 15, 2016 at 7:32
• I should also have mentioned that I'm getting this error message: Package tikzposter Warning: Unknown Option draft. on input line 204. I don't get this error in the separate 'project', however. So is this the culprit? Sep 15, 2016 at 7:36
• OK, I solved this by copying all my code and files into a new 'project'. The images now work perfectly and the error messages don't reappear. Since nothing else has changed I assume this is a bug with Sharelatex so I'll close this question. Sep 15, 2016 at 7:46
• draft option is the culprit. draft option from graphicx does the result you get. Some of your files introduces it. Sep 15, 2016 at 7:47
