# Adding a background image with tikz poster

When using the tikzposter package, is it possible to add a background image?

I currently have a colour gradient, and would preferably like to keep this intact, and superpose the image on top of that.

The current document looks somewhat like this:

\documentclass{tikzposter}
\tikzposterlatexaffectionproofoff

%% colors
% title
\definecolor{backgroundcolortop}{RGB}{255,255,255}
\definecolor{backgroundcolormiddle}{RGB}{255,255,255}
\definecolor{backgroundcolorbottom}{RGB}{91,195,240}

\title{Ttile}
\author{{\LARGE Authors}\\{\normalsize email}}
\institute{{\Large Institute}}

\begin{document}
\titleblock[seperated=false, embedded=true]
%...
\end{document}

Please provide a minimal, but complete version of your document, showing the relevant settings; in particular, we need to see the settings for the current colour gradient you mentioned. –  Gonzalo Medina Jun 26 at 4:43
I think this is not provided out of the box in the current version. Please be patient, the guys from this class and two other people work on an extended tikzposter class: tex.stackexchange.com/a/120988/14200 Try fancytikzposter to change your background. –  Dirk Jun 26 at 6:43
