Beamer: How to show images as step-by-step images

I'm trying to make a presentation using the Beamer class. I want to show a simple list of images, one by one in one frame, just like when you use itemize<+->.

I have no problem showing the images one-by-one, but the images shifts every time I insert a new image. How do I solve this - From my perspective there must be a simple solution, without specifying the absolute placement of the images.

You can simply specify a series of images like this:

\includegraphics<1>{A}
\includegraphics<2>{B}
\includegraphics<3>{C}

This will produce three slides with the images A to C in exactly the same position.

I found a solution to my problem, by using the visble-command.

EDITED:

\visible<2->{
   \textbf{Some text}
   \begin{figure}[ht]
       \includegraphics[width=5cm]{./path/to/image}
    \end{figure}
