The easiest way to do this that I have found is to provide overlay specifications to the elements of the picture. The basic commands, \path, \draw, \node and so forth are all overlay-aware. The one thing to be ware of is that the bounding box might jump around a bit as different parts of the drawing are put in or taken out. However, once you're aware of ...

This is due to the way that \pause works. As beamer processes a frame, it has an internal counter beamerpauses which it uses to work out what the current "logical" slide is. This is for use when you want to specify an overlaid command without referring to a specific slide, which is useful if you don't know (or haven't yet decided) what the specific slide ...

An interactive version with beamer may be constructed along the following lines:
\documentclass{beamer}
\begin{document}
\begin{frame}[fragile]%
\begin{semiverbatim}
\frametitle{Input \&\ Output}
\#include <cstdio>
\only<1>{(1)?}\only<2->{int main() \{}
\only<3>{(3)?}\only<4->{long a,b,c;}

From the beamer manual, in the middle of a use case:
Euclid finds that he can also add a \pause between the definition and the example. So, \pauses seem to
transcede environments, which Euclid finds quite useful. After some experimentation he finds that \pause only does not work in align environments. He immediately writes an email about this to ...

Yes, \pause inserts "something" on an empty line in your instance. You could get rid of it by "jumping back" a line using \vspace*{-\baselineskip} before \pause:
\documentclass{beamer}% http://ctan.org/pkg/beamer
\begin{document}
\begin{frame}
Without pause:
\[A\]\[B\]
Not too much space between displayed equations.
\end{frame}
\begin{frame}

It's not much different than what you have already.
\documentclass{beamer}
\usepackage{mwe} % For dummy images
\usepackage{lmodern} % To suppress some warnings
\begin{document}
\begin{frame}
\centering
\begin{tabular}{c@{}c}
\includegraphics[width=0.4\textwidth,trim=0 120 160 0,clip]{example-image-a}\pause%

You can escape to LaTeX (Section 4.14 Escaping to LaTeX of the listings documentation) and use \pause:
\documentclass{beamer}
\usepackage{listings}
\usepackage{bera}
\lstset{basicstyle=\small\ttfamily,
numbers=left,
escapeinside=||
}
\begin{document}
\begin{frame}[fragile]
\begin{lstlisting}
line1 |\pause|
line2 |\pause|
line3
\end{lstlisting}
\end{frame}

You can use \only:
\documentclass{beamer}
\setbeamercovered{dynamic}
\begin{document}
\begin{frame}
\centering
\only<1->{\includegraphics[width=4cm]{ctanlion}}
\only<2>{\includegraphics[width=4cm]{ctanlion}}\par
\end{frame}
\end{document}
To preserve the relative position in slide one, you can use overlayarea:
\documentclass{beamer}

That's some curious behaviour you observed! There's nothing inherently wrong in the syntax you use – I'll explain below why the output goes awry nevertheless. Neil's suggestion to use \begin{itemize}[<+->] is a great alternative to \pause in your example. If you want to use \pause all the same, then there's an easy fix: adding an empty line (or a ...

This is covered in Section 17.6 on page 191 of the beamer manual.
\setbeamercovered{invisible}
hides the content completely. Note that, the content which is already presented and become transparent and the content that is still about to be presented can be distinguished with the options of this command.

It's a sync problem; if you add \thebeamerpauses in some places (to get the value of the beamerpauses counter), you can see what's going on:
\documentclass{beamer}
\usepackage[utf8]{inputenc}
\usepackage{default}
\begin{document}
\begin{frame}
\begin{itemize}[<+->]
\item A\thebeamerpauses
\item B\thebeamerpauses
\item C\thebeamerpauses

I don't have my LaTeX here, but this ought to work. You have to rewrite each \pause to proper <n-m> syntax.
\begin{frame}
\frametitle{An example}
\only<1>{
insert a picture for instance
}
\only<2-3>{
\begin{itemize}
\item<2-3> here is my first remark
\item<3-3> and here is my second
\end{itemize}
}
\only<4>{
insert a 2nd ...

(Posting this as a separate answer since I seriously propose the code here as a bug fix for beamer, or maybe even better for pgfsys-pdftex.def.)
In the end I found out the real cause of my trouble: beamerbasecolor.sty redefines the \reset@color command, and the redefinition contains the line
\pgfsys@color@unstacked{beamer@tempcolor}%
The pgf manual ...

Finally I followed Joseph's advice, and in the end found an easy fix for my problem: redefine \beamerorig@set@color and \beamerorig@reset@color to what they were before 2007. With the code below, the \pauses work exactly like expected:
I also tested this with two sets of real-world slides, and encountered no unwanted side effects.

I think the problem is that \pause isn't smart enough. The footline appears in the following:
\documentclass{beamer}
\providecommand\thispdfpagelabel[1]{} % Not sure what this does but our installation requires it.
\usepackage{tikz}
\usetheme{Madrid} % Has a footline.
\begin{document}
\begin{frame}
\frametitle{test}
\begin{tikzpicture}

It is not possible :-(
This is clearly stated on page 60 (§8.1) of the beamer manual in the documentation of the allowframebreaks option:
allowframebreaks=⟨fraction⟩. When this option is given, the frame will be automatically broken up into several frames if the text does not fit on a single slide. In detail, when this option is given, the following ...

Have a look at section 9.6.4 and section 23.1 of the beamer manual: You can use a dot in the overlay specification (e.g. <.->). The dot is replaced by the current value of beamerpauses minus one, so if you use \item<.->, this item is shown simultaneously with the previous \item.
For example, if you have a list with four items and you want to ...

By putting the \section command inside the frame environment you are ensuring that it is executed for each overlay of that frame. The use of the \pause command then ensures that this is done more than once. So LaTeX thinks that you have three sections called "Study Background" because that particular \section command is executed three times.
It is ...

Delete the \noalign command from the definition of \cellcolor:
\documentclass[xcolor=table]{beamer}
\rowcolors{1}{gray!30}{gray!10}
\makeatletter
\def\rowcolor{\noalign{\ifnum0=`}\fi\bmr@rowcolor}
\newcommand<>{\bmr@rowcolor}{%
\alt#1%
{\global\let\CT@do@color\CT@@do@color\@ifnextchar[\CT@rowa\CT@rowb}%

As Daniel mentioned in his answer, it's not possible to use frame breaks and overlay specifications; however, using a beamercolorbox (or an appropriate variant, depending on the theme used) you can define a new environment that behaves as the proof environment, except for the title, and then you can use this new environment to write the successive parts of ...

There is special syntax for item's - I've never tried pause with lists for that reason, but my guess is that it's causing trouble. Try removing all the pauses and replace \begin{itemize} with
\begin{itemize}[<+->]
This causes each item to be uncovered one by one. For more fine-grained control, instead of the above change, use e.g.
\item<3->

You could use TikZ and put the pictures in nodes. With no inner sep or outer sep they align perfectly. If you need spacing, you can use <position>=<distance>, like above right=3mm
Code
\documentclass{beamer}
\usepackage{tikz}
\begin{document}
\begin{frame} \frametitle{Cufflinks analysis - SRSF1}
\begin{figure}[t]
\begin{center}

As you are aware, beamer will create a new page for each overlay. Each time a page containing a lstlisting environment is created the counter lstlisting is incremented. As this goes for any counter (tables, figures, etc.) beamer supports resetting the counter on overlays. Place
\resetcounteronoverlays{lstlisting}
in the preamble and your problem should be ...

In the beamer user guide, in the explanation of \pause it says:
This command does not work inside amsmath environments like align, since these do really wicked things.
The wicked thing that align, gather and friends do is that they evaluate the contents of the environment twice. In particular, overlay commands such as \pause are executed twice, which ...

The following MWE provides \hidecontent[<transparency>]{<stuff>} that hides <stuff> with a white transparent box. Optional transparency is set as <transparency> (provided by Heiko's transparent package); default is 0.25 or 25%:

The easiest is to use the overlay specification [<.->] in the itemize environment. You can check the difference with the following code that I modified the one in the manual page 92 (v.3.12):
\documentclass{beamer}
\begin{document}
\beamerdefaultoverlayspecification{<+->}
\begin{frame}
\begin{itemize}
\item Apple
\item Peach
\item Plum

Possibly not the answer you're after, but it can be useful. The idea is to use \onslide instead of \pause; this, however, will produce still an undesired effect: the last equation number will appear on every slide, as can be seen in the following example:
\documentclass{beamer}
\begin{document}
\begin{frame}
\begin{gather}
\onslide<1->{1\\}
...

I think you need the \onslide and \alert commands of the OVERLAY section of the Beamer's manual.
\documentclass{beamer}
\begin{document}
\begin{frame}[<+-|alert@+>]\frametitle{Title}
\begin{block}{Title}
\begin{itemize}
\item A
\item B
\item C
\end{itemize}
\end{block}
\begin{block}{Title}
\begin{itemize}
\item A
\item B
\item C

Now that we understand that the \pause functionality has not changed, I have interpreted the question as "How can I get \pause to make images transparent too?"
And for that, I have one possible workaround. I am not sure how robust it is, but essentially I have attempted to replace the pgf transparent mechanism with the version in the transparent package ...

I'm sorry, but I made a mistake when I posted my question. When I ran my simple file under texlive2011, the file did not have the following line:
\setbeamercovered{transparent=10}
But when I tested the file under texlive2012, I inserted the above line. That made the difference. After removing that line, the pdf file created under texlive2012 exactly ...
