Graphics, Figures & Tables ⇒ Beamer .jpg pictures ontop of each other

[Mikerada6]

I am using TexNicCenter, and MikiTex with the beamer class. For one of my slides i have four pictures that i want to be displayed on top of each other one after the other. i tried using the code

Code: Select all

\DeclareGraphicsRule{*}{jpg}{*}{}
\multiinclude[graphics={height=5cm}]{rec-1}
\multiinclude[graphics={height=5cm}]{rec-2}
\multiinclude[graphics={height=5cm}]{rec-f}
\multiinclude[graphics={height=5cm}]{spiral}

but i get the error message
Package pdftex.def Error: File 'rec-1.0' not found.

What am i doing wrong?
