I have to make a book cover for my document which must have a png image covering all the height of the left page margin. The rest of the page must have pictures, and text lines centered.

Something like the following coverpage:

enter image description here

How could I do it?

All I can get is to fill with a color the left side of the page


\title{\tikz[remember picture,overlay] \draw [fill,red!20] (current page.north west) rectangle +(0.33\paperwidth,-\paperheight);%
Rather Long Document Title to Show that the Colour is Behind the Title}
\author{John Doe}



but not to insert an image.

Thank you very much for your help.
