You can use the background package which internally relies on tikz to place either an imported graphic logo or a logo created with a tikzpicture on each page or on selected pages:

The code below places the image on each page. However, if you only want to place the logo on some of the pages you would simply load the package with the some option:
\usepackage[some]{background}
and then issue the \BgThispage on the pages where you wanted the logo. An example of including the image on specific pages (ex, 2, 3, and 6) can be found in Image on top specified page.
Note
- Need at least two runs to see the logo.
Code:
\documentclass[12pt]{article}
\usepackage[demo]{graphicx}
\usepackage[all]{background}
\usepackage{lipsum}
\usepackage{showframe}
\usepackage{tikz}
\newcommand{\MyGraphicLogo}{% For imported graphic logo
\begin{tikzpicture}[remember picture,overlay,yshift=-2cm, xshift=2cm]
\node at (0,0) {\includegraphics[width=2cm,height=2cm]{foo}};
\end{tikzpicture}
}
\newcommand{\MyTikzLogo}{% For a logo drawn with TikZ
\begin{tikzpicture}[remember picture,overlay,yshift=-1cm, xshift=1cm]
\draw [cyan,fill=yellow] (0cm,0cm)
-- (2cm, 0cm)
-- (2cm, -2cm)
-- (0cm, -2cm)
-- cycle;
\end{tikzpicture}
