# How to include two team member's photo in titlepage in beamer?

This question is an extended version of How to align multiple author's name, roll, institute in titlepage in beamer?. And the viewing the photo in circle is taken from How to show circled portion of a image in beamer slide?

I want to make a slide with two author's name, roll, and photo. I can easily add author's name, and roll, but when I include their photo the content of the slide is gone.

My trying source code is here -

\documentclass{beamer}
\usepackage{tikz}
\logo{%
\includegraphics[width=1cm,height=1.5cm,keepaspectratio]{example-image-a}%
\hspace{\dimexpr\paperwidth-2cm-5pt}%
\includegraphics[width=1cm,height=1cm,keepaspectratio]{example-image-b}%
}

\begin{overlayarea}{\textwidth}{\textheight}

% coordinates, I do not have your original picture

This is combination of various problems:

• missing or misplaced parenthesis caused text outside of a frame environment. Beamer tried to rescue this situation by inserting an additional frame

• as @marmot already explained in his comment, overlayarea are to be used in combination with overlays

• if you mess with the author definition instead of redefining the title page template, the same definition will also be used for the authors in the footline, thus causing additional images on the bottom of the frame. You can rescue this by giving short author names, but IMHO it would be better to redefine the title page.

• your title and institute are too long for the footline, you should give a short alternative
